Request SSR configuration help

[Yang Bingan]

Dear SSR Users,

Greetings!

My name is Bingan Yang, a beginner of Linux without much experience of Linux which installed in VMware Workstation 14.

* All commands run at root privileges for installation and configuration, all dependencies are successfully installed by "apt-get","./configure" show up a summary that we are ready to compile(disabled IP interface);
* ssr unpacked file root folder: /home/bingan/Downloads/ssr-0.4.2.

Currently, I have encountered some problems and have been stuck here for around two weeks

1) "./configure"again but below error shows up:

checking for boost_system library... not found! (Use BOOST_LIB_DIR to specify a directory.)
checking for boost_thread library... not found! (Use BOOST_LIB_DIR to specify a directory.)

Attempts: ./configure BOOST_LIB_DIR=-I/LIB64, but still not working

Question:
Manual PDF "Ensure that /etc/ld.so.conf or LD_LIBRARY_PATH are set properly, and run ldconfig after changes."

 Q: How to ensure the path is correct? Which library path should be set? Currently,  /etc/ld.so.conf file has content " include /etc/ld.so.conf.d/*.conf", how do I change the  "*" into a path? Or "BOOST_LIB_DIR" has no value in "configure"file at /home/bingan/Downloads/ssr-0.4.2. Do I need to give a value? How to do so?

2) Manual PDF"If a header is not installed in the standard paths of your system you can pass its location to the configure script using ./configure CPPFLAGS=-Iyourpath"

Question: which path should be used? What header this means for? I have tried to run "./configure CPPFLAGS=-I/lib64" but it shows error.

3) run "qjackctl" command shows up:
QStandardPaths: wrong ownership on runtime directory /run/user/1000, 1000 instead of 0
No protocol specified
qt.qpa.screen: QXcbConnection: Could not connect to display :0
Could not connect to any X display.

Question:

a) how to change the standard path?

b) how to specify a protocol?

c) how to get QXcbConnect works?

4) Previously it seems have been installed successfully in the VMware Debian 9.x 64bit system and the Qjackctl can open up Jack Connect Kit, however once loaded a 720 channels WAV file(origin: http://usir.salford.ac.uk/30868/) it takes endless time to load the file(90M size) to the server, furthermore, open the "connect" tap but no devices can be detected in the "Audio" tap while "MIDI" exists some hardware.

Attached file is a Configuration Log, appreciated for your kindness to read this email and really expect your helps to solve these problems for listening the spatial audio performance in a listening room at Salford.

Best regards

This is not good. You should use root only where necessary.

Linux is case sensitive, are you sure the directory is called /LIB64
and not /lib64?

Also, you should not use "-I", but just the directory.

And, /lib64 should be searched by default, are you sure your boost
libraries are there?

Wherever the boost libraries are located on your system.
You can search for files that start with "libboost" and end with ".so".

I'm still not sure if your really installed all the necessary packages.

Which boost-related packages did you install?

> Currently, /etc/ld.so.conf file has content " include

You shouldn't.

Just leave the line as it is and add more paths in separate lines.

But you probably don't need all this, let's first make sure you have
installed Boost correctly.

You don't have to change the "configure" file.
The way you used it in your configure call looks fine.
But you probably don't need this anyway.

This is for adding header files (i.e. files with the ending ".h" or
".hpp"). This is not relevant in your case.

This is because you were using root for configuration.
You should do everything as a normal user and only "make install" as root.

You should also make sure that you start the JACK daemon with the same
user as you are using for the SSR (which should not be "root").

BTW, you should also make sure that your user is member of the "audio" group.

How exactly did you "load" the file?

OK, that's bad. There should be at least one entry called "system" in
the Audio tab.

Did you press "Start" and did JACK start successfully?

I've never used VMware, but you probably have to configure it in some
way that the audio device is available to the guest OS?

Probably someone else on this mailing list has experience with VMware?

Good luck, and if you have further questions, don't hesitate to ask!

Welcome to the world of Linux and to the SSR community!

@Thank you, it is my pleasure to join the SSR community.

This is not good. You should use root only where necessary.

@Created a new folder 'try_16Dec', copy and unpack ssr-0.4.2.tar.gz into the new folder, right click to open in terminal, then run through the commands (a normal user), firstly,./configure then get the same finding as Question 1 below.

Linux is case sensitive, are you sure the directory is called /LIB64
and not /lib64?

@sorry, /lib64 is correct

Also, you should not use "-I", but just the directory.

@deleted -I

And, /lib64 should be searched by default, are you sure your boost
libraries are there?

@cannot locate the boost libraries

Wherever the boost libraries are located on your system.
You can search for files that start with "libboost" and end with ".so".

@searched files "libboost" but no result, I guess I have missed something

I'm still not sure if your really installed all the necessary packages.

@all the dependencies in Page 8 are installed by manually use apt-get install "make ... etc"

Which boost-related packages did you install?

@I have no idea what packages are boost-related packages, for example:libboost-dev

> Currently,  /etc/ld.so.conf file has content " include
> /etc/ld.so.conf.d/*.conf", how do I change the  "*" into a path?

You shouldn't.

Just leave the line as it is and add more paths in separate lines.

But you probably don't need all this, let's first make sure you have
installed Boost correctly.

@noted, may I know what is Boost? Is it libboost-dev package?

This is because you were using root for configuration.
You should do everything as a normal user and only "make install" as root.

@noted, now do it again in the new folder and root is required to install dependencies, so use root to install then ./configure, but same finding as Question1

You should also make sure that you start the JACK daemon with the same
user as you are using for the SSR (which should not be "root").

@noted, will use as normal user

BTW, you should also make sure that your user is member of the "audio" group.

@root user, key in commands "adduser bingan audio" shows bingan is already a member of audio group

How exactly did you "load" the file?

@normal user, key in "qjackctl" to open <Jack Audio Connect Kit[(default)] Stopped> then click Start tap, pop up window shows "Could not connect JACK server as client  -Overall operation failed  - Unable to connect to server  - Please check the messages window for more info."

 

@check the directory but no such file "/dev/shm/..."

OK, that's bad. There should be at least one entry called "system" in
the Audio tab.

@cannot locate the system

Did you press "Start" and did JACK start successfully?

@I am not sure whether it start successfully, I can see the window is showing the progress status and RT 4% varying; now press"Start" and error as above, JACK ALSA shows below, Audio MIDI no devices detected

Hi Matthias,

Good news:

The question 1 is settled by running below commands to install the libraries:

1) sudo apt-get install libboost-filesystem-dev

2) sudo apt-get install libboost-thread-dev

And now try to solve the JACK issues.

Thanks

Hi Bingan,

I'm not sure if that's the issue, but your JACK settings are very aggressive. You set the frame size (a.k.a. block size, buffer size)  to 16 samples ("Frames/Period") and "Periods/buffer" to 2. Start with 1024 and 3 and then lower the frame size if the latency is too large.

Greets,

Jens

Dear Jens,

Noted with thanks.

I have just changed the setting as advised, please refer to below screenshot. However the issue still exists, I have tried to uninstall libjackd-dev and then install libjack-jackd2-dev, uninstall jackd and install jackd2 only. The number of problems become less and the messages become pink font rather than black; then restart qjackctl, the problem resurfaces. I am wondering whether there is something wrong with the dependencies installed. Could you advise whether all of the dependencies should be installed? For example, libecasoundc2.2-dev is unable to install while libecasoundc-dev is ok.

In the mean time, how to ensure the configuration are correct? Don't mind if anyone of you can add my Skype ID (bingan yang) for troubleshooting, I am struggling to configure ssr for two weeks however it is very disappointing that I still cannot get it work.

Regards

Bingan

Hi Bingan.

It's good to see that you are making progress!

I've just lost track about what's the current issue. What is the actual problem?

Is there anything not working as expected?

According to your last screenshot, JACK is running (it says "Started" in the top left of the display area), there are just some xruns happening (the red numbers below "Started").

So you should be able to use the SSR, but there might be some audio dropouts.

The logging messages suggest that there are problems using realtime (RT) mode.

You said before that your user account is part of the "audio" group, which is one requirement for that.

Just to make sure, please run the command "groups" and check if "audio" is in the list.

But also the JACK daemon has to be configured correctly in order to use realtime priority.

To do that, you should run this command as root:

    dpkg-reconfigure jackd2

... and answer "Yes" to enable realtime priority.

I'm not sure if it's necessary, but you should probably re-boot the system afterwards.

Once everything works, you can try to switch "Periods/Buffer" back to 2 and see if it still works.

cheers,

Matthias

Dear Matthias,

Noted with many thanks for your kind following up.

1) run the "groups" and audio is in the list as below shown:

bingan cdrom floppy audio dip video plugdev netdev bluetooth lpadmin scanner

2) run "sudo dpkg-reconfigure jackd2" and then select "Yes", reboot Debian and VMware, then run qjacktrl and configure "Periods/Buffer" back to "2" then error as screenshot; 

Change back to 1024 Periods/buffer, no error shows as below and the Messages as Appendix A shown.

3) the current issues:

   a. Jack still shows error as Appendix B;

   b. When Jack started, the audio shows only system where has two mic and two loudspeakers, I would like to test the system mics either headset mic or computer        embedded mic in laptop.

   c. Tried to load the snaredrum.wav file but the error shows in Appendix C:

If you don't mind, shall we arrange half an hour for Teamviewer troubleshoot? That will be more efficient to resolve all these tricky issues in one shot.

Thank you so much

Bingan

[Jens Ahrens]

Hi Bingan,

As far as I can tell, the messages in your Appendix A are uncritical. See also this thread: https://github.com/jackaudio/jack2/issues/226

Regarding your issue a ("Jack still shows error as Appendix B"):
As per the thread referenced above, there seems to be no actual error but rather an unfortunate JACK message.

Regarding your issue b ("When Jack started, the audio shows only system where has two mic and two loudspeakers, I would like to test the system mics either headset mic or computer embedded mic in laptop."):

Presumably, it's your operating system that switches between headphone out and loudspeakers. JACK only sees the same two output channels. That's how it at least happens on my MacBook. I can plug and unplug the headphones while JACK is running - which causes the operating system to switch between the different physical outputs -  but JACK will not notice a difference.

Regarding your issue c ("Tried to load the snaredrum.wav file but the error shows in Appendix C"):

Specify also the filename extension when calling ssr ("ssr snaredrum.wav" instead of "ssr snaredrum"). If that still doesn't work, there might be something wrong with the header of the file. In this case, install sox and do:

sox old.wav new.wavpcm
mv new.wavpcm new.wav

(as explained at the bottom of this section: http://ssr.readthedocs.io/en/latest/operation.html#make-dmg-on-mac-os-x-chokes-on-symbolic-links)

This creates a new header for the file the libsndfile understands.

Greets,

Jens

[Yang Bingan]

Dear Jens,

Good news update.

Appreciated for your kind help, now the SSR interface is visible and the binauralrender in the audio is also appeared, but there is no sound output from loudspeakers. Kindly see below.

Hi Bingan.

You might be missing a package named "ecasound"?

I've just seen that the documentation of the dependencies in the PDF file of SSR version 0.4.2 isn't very good.

We have improved that in the meantime. Have a look at this page to double-check if you have all the necessary packages installed:

https://github.com/SoundScapeRenderer/ssr/blob/dc3ab1b387fbad53dc392b27fe09392f9e7a303a/doc/manual/operation.rst#dependencies

Good news update.

Appreciated for your kind help, now the SSR interface is visible and the binauralrender in the audio is also appeared, but there is no sound output from loudspeakers. Kindly see below.

Hi Bingan,

Merry Christmas to you, too!

I'm not sure if I understand correctly: SSR runs and it opens the audio file. When you hit "play" it keeps running, but you can hear no output. Is that correct?

If yes, then we need to clarify the following:

- Does you system play output at all? If not, the problem might be somewhere else...

- Does any other JACK-based software play properly? Test it, for example, with ecasound using the following command:

ecasound -i YOUR_AUDIO_FILE.wav -o jack,system

(The assumes that your sound card ports in JACK are named "system:...")

If this runs but does not cause output, it might be worth double-checking the alsa mixer settings. Run "alsamixer" in the command line. You can use the arrow keys and navigate to the different slider and pull them up. Sometime they are all the way down by default.

Let us know what happens.

Greets,

Jens

[Nachricht gekürzt]  

[Yang Bingan]

Dear Jens,

Thank you.

Yes, you are right. Run alsamixer command and adjust all the sound cards to appropriate level and keep checking before playing audio file.

Run ecasound command and play the audio three times, test ok. However when run SSR again, the audio is like playing bit by bit; then change the setting in QjackCtl Setup frames/period from 1024 to 4096, period/buffer to 3 then the audio playback become longer, for instance, 0.3s then pause for a second then 0.2s or 0.3s. Noticed that there are some audio samples are skipped in the Messages window.

Attempts:

1) uninstall Jackd2 and install Jackd1, restart OS then ./configure, make && make install(root) again, but the audio playback is playing bit by bit

2) play audio file by video/VLC directly, audio is ok;

3) tried the website solution but still cannot resolve this problem

Thank you very much for your advice and help

Regards

Bingan

Dear Bingan,

Great, we're narrowing down the problem. It seems that your installation is ok.

JACK reports XRUNs, which means that it happens sometimes that SSR requires more time to process an audio frame than what is the duration of that audio frame. This causes the drop outs of the audio output. It can have many reasons. We have never seen SSR causing this directly.

Reasons that I can conceive are:

- Reading an audio file with too many channels. We've seen that many times, the speed of the hard drive is a bottleneck. SSR can easily handle dozens (or hundreds, depending on which renderer your using) of virtual sound sources. But reading more than 20 channels can be an issue especially with older hard drives. Check this.

- Streaming the audio file from a remote source (network drive etc.) can also cause this.

Try and simplify your setup as much as possible to narrow down the problem (short audio file with only few channels etc.). Run SSR and do some profiling to see what causes the long processing times (use, for example, the command "top"). Also check what the computational load is if you are playing your audio file directly to the sound card via JACK and ecasound (using the command from my previous message). SSR uses ecasound to play the files, too.

Best regards,

Jens

[Yang Bingan]

Dear Jens,

Thanks for your advice.

-- use either 1-channel or 2-channel wave file, but the error still happen that XRUN callback (#, skipped)

Q: how to know jack is currently capturing how many channels? this might help to pinpoint the issue.

Note: previously loaded 720 channels audio file and display all the source locations at the SSR GUI, this might cause SSR collapse? I have ever loaded for some times and the problem is that audio level is not varying.

-- check alsamixer: all maximized level

   check ecasound -i audiofile.wav -o jack,system: music playback is intermittent bit by bit which might be because of the XRUN callback skipped(JACK setting frames 4096, period 3; if change to 1024/3, the music playback bit is become shorter than 4096);

   change the timeout setting to 5000 then playback can be much longer but it is not consistently long during every playback.

- try different wave file then notice the alsa mode is"writte", should this be correct?

-- ecasound seems like working in the way that read bits of music then write bits of music to ALSA to playback? this caused the noncontinuous playback(some frames skipped in XRUN)

-- use top to check the process as below: 1) running ecasound only(40% to 80% CPU); 2) running SSR (90% to 100% CPU)

Above are all I can find now, it is very time-consuming to get it work and I hope I can resolve these in the coming days otherwise I have to give up because I am too much behind my project schedule.

Thank you for your helps.

[Jens Ahrens]

Dear Bingan,

Your problem is definitely independent of SSR. If ecasound by itself causes 40-80 % CPU load, then something's very wrong. It could be related to your sound card driver or all sorts of other things. BTW, in the ecasound example you're providing, there are different sampling rates apparent. It could be that there is some online re-sampling going on, which can cause a bit of CPU load.

Other than that, there is nothing that I (or probably we) can do for you. A problem like yours cannot be solved remotely. It's too specific to your particular system. You might want to try it in the according forums (JACK or ecasound or linux audio or so). Maybe you can get help there.

Sorry for not being able to resolve your problem!

Jens

Dear Jens,

Thank you so much for your advice and I am very fortunate to have your supports, I will make all efforts to resolve this problem(maybe reinstall a different OS).

Dear Jens,

Great news!

With the whole day working on this, I found the reasons why the audio skipped by below:

1) because Linux is running at VMware where VMware shared the hardware(like sound card) with Windows OS; when disconnected the sound card in VMware the audio signal plays back smoothly but simply no sound playback because of disconnected;

2) before the step 1, I have done all necessary re-installation of all packages but unfortunately it doesn't help; so decided to install Linux OS in USB Thumbdrive(16GB) and installed all necessary dependencies, then the problems in the above email only happen once that "Cannot connect to JACK server...", this can be simply resolved by changing the setting of JACK interface to (hw: 1,0), in the meantime, the CPU is still working smoothly at 10% usage.

3) Because of the sound quality of the system sound card, the music quality is lossy and makes the spatial effect less detailed; next step which I am trying to do is to install RME Fireface UC Linux driver/firmware, however I cannot find the driver in Linux(will continue to source out this).

Appreciated your supports and patient helps, sometimes I felt upset because of spent too much time in setting this up but still cannot manage to listen the spatial audio effects. Went through all the difficulties, your detailed explanations always keep us upheld and I cannot help to express my greatest honor to you whom are the great developer in SSR community.

Best regards

Bingan

[Jens Ahrens]

Hi Bingan,

I'm glad that things are resolving for you. Linux can be like that...

If I remember correctly, then RME drivers are actually provided by ALSA. Some 10 years ago, it was necessary to run hdspmixer or something similar once after booting so that the audio interface woke up. Maybe this has changed. There is also the RME forum: https://www.forum.rme-audio.de/index.php

I'm using Mac OS now. ;)

Good luck!

Jens

[bing]

Hi Jens,

Thanks for providing further information and I will check whether the ALSA packages installed will work with the Fireface UC. If not were you telling about the history of the ALSA and RME, I will definitely not notice that transition. I might consider to purchase one MacBook as well. :)

Best regards 

Bingan

JACK reports XRUNs, which means that it happens sometimes that SSR requires more time to process an audio frame than what is the duration of that audio frame. This causes the drop outs of the audio output. It can have many reasons. We have never seen SSR causing this directly.

Reasons that I can conceive are:

- Reading an audio file with too many channels. We've seen that many times, the speed of the hard drive is a bottleneck. SSR can easily handle dozens (or hundreds, depending on which renderer your using) of virtual sound sources. But reading more than 20 channels can be an issue especially with older hard drives. Check this.

- Streaming the audio file from a remote source (network drive etc.) can also cause this.

Try and simplify your setup as much as possible to narrow down the problem (short audio file with only few channels etc.). Run SSR and do some profiling to see what causes the long processing times (use, for example, the command "top"). Also check what the computational load is if you are playing your audio file directly to the sound card via JACK and ecasound (using the command from my previous message). SSR uses ecasound to play the files, too.

Best regards,

Jens

Dear Jens,

Thank you.

Yes, you are right. Run alsamixer command and adjust all the sound cards to appropriate level and keep checking before playing audio file.

Run ecasound command and play the audio three times, test ok. However when run SSR again, the audio is like playing bit by bit; then change the setting in QjackCtl Setup frames/period from 1024 to 4096, period/buffer to 3 then the audio playback become longer, for instance, 0.3s then pause for a second then 0.2s or 0.3s. Noticed that there are some audio samples are skipped in the Messages window.

Attempts:

1) uninstall Jackd2 and install Jackd1, restart OS then ./configure, make && make install(root) again, but the audio playback is playing bit by bit

2) play audio file by video/VLC directly, audio is ok;

3) tried the website solution but still cannot resolve this problem

Thank you very much for your advice and help

Regards

Bingan
