Trying to port alsamixer with ncurses

[Huy Minh Bui]

Hi, I'm trying to compile alsamixer tool for nougat-x86. I'm using libncurses source from LineageOS : https://github.com/LineageOS/android_external_libncurses 

After modified Android.mk and aconfig.h to point it into libncurses and try to build it. But I'm having some linking problem here.

Deleted it but the error is still the same

You need to identify the source and the static library providing for the missing symbols

Example:

error: undefined reference to 'unpost_menu'

cd external/alsamixer

cgrep  unpost_menu

then check if you need to add some source to the list for alsamixer module

or if you need to add some dependency

Hi Mauro, thanks for your reply
I found that all of those references are in libncurses source. But actually, your reply made me think about reading Android.mk in that libncurses again and found out that there are 2 more libs that need to compile : libmenu and libpanel

I'll try again tomorrow. Thanks for helping me pointed it out.

[Huy Minh Bui]

It just alsa_amixer with ncurses UI, maybe you need a newer kernel or some modprobe trick.

Hi HM, Can i fix my primeos no-sound problem via this method?

[Huy Minh Bui]

Final result : after compile the full libmenu, libpanel and libform, alsamixer can be compiled.

The result impressed me 

With tty everything works fine with full function as expected

With some Terminal apps like Terminal Emulator and Termux ncurses is a bit broken. Changing volume work however pressing Fx keys to change deivces, see help or show info make the program broke. Maybe it act as characters instead of Fx keys since when I press it, it close my program and show some characters after that.

Anyway here is what I did :

https://github.com/hmtheboy154/external-alsa-utils

https://github.com/hmtheboy154/android_external_libncurses

I hope this tool can come to Android-x86 since there are many people feel it hard to use amixer command :D.

Thank you!

It's been almost a year since I wrote this post. And I've been cleaning up the source a bit so that you can merge it easier.

One thing that I can't do so far is to copy terminfo folder into /system/etc while building the OS, so I need some help with that. Anyway, tinkering with the tool is more easier than typing amixer command, so I hope that we can have it on the next Android-x86 release.

Thank you for the update.
I'm too busy recently so I almost forgot it. Sorry!
Will check it when I have time.

What's the problem to copy terminfo?
I saw you used LOCAL_POST_INSTALL_CMD in Android.mk.
That should work. Isn't it?
Though adding it to ALL_DEFAULT_INSTALLED_MODULES is unnecessary.

I hope to clean it up further. For example,
I believe the generated Makefile and binaries
are not used by android. They could be removed.

[Huy Minh Bui]

that LOCAL_POST_INSTALL_CMD only works if /system/etc existed. So when you start to compile the whole rom from the beginning it will fail and you have to mkdir it manually. That's why I left it there

But today I saw that Jon make it work by reusing LineageOS's code : Include terminfo again · BlissRoms-x86/android_external_libncurses@f10b074 · GitHub

I hope so, because the source seems messy after I run ./configure

Sorry for replying so late.

I just have some time to work on it.
The alsa_alsamixer and libncurses are added to oreo-x86 and later.
I didn't use your libncurses repo directly. But it helps a lot! Thank you!
I worked out a way to generate all the files at build time.
Except Android.mk no additional file is added.

About LOCAL_POST_INSTALL_CMD issue, it's easy to be solved
by adding mkdir -p $dir to it.
But I didn't use it at all. I built libncurses with fallback support
so it doesn't need any terminfo files.
However, only term type 'linux', 'xterm', 'vt100' are supported.
I think that's enough.

[Huy Minh Bui]

Thanks for helping me rewrite the sources, now they all look nicely done and better. :D 

Although I can't compile on nougat-x86 since there are some part on Android.mk is only available on oreo, but it's fine, we have a better source for future Android version now.

by the way, one more thing I'd like to ask is that how can I use 2 prop "audio.hal.in" and "audio.hal.out" to switch the input/output for audio. There are a few people putting it on init.sh script or build.prop but it just work like randomly (sometimes it work, sometimes it doesn't) so I want to know where should I put so that it will effectively work 100% all the time ?

The properties are "hal.audio.out" and "hal.audio.in".
Typically the audio hal will select the first playback device
(usually /dev/snd/pcmC0D0p) and first capture device
(usually /dev/snd/pcmC0D0c). If they are not the devices
you want to use, you can use these properties to set the
device name, e.g., setprop hal.audio.in pcmC0D1c
Then restart audioserver by 'killall audioserver'.
Check the logcat to see if it works:

06-24 11:06:56.990 6395 6444 I audio_hw_primary: using pcmC0D1c from property
06-24 11:06:56.990 6395 6444 D audio_hw_primary: found audio in at
/dev/snd/pcmC0D1c
06-24 11:06:56.990 6395 6444 I audio_hw_primary: choose pcmC0D1c for 0

If the properties not work, probably because they are set after
audioserver started. Just restart audioserver as said above.

If you set them in /etc/init.sh but not work randomly, probably
there is a race condition between init.sh and audioserver.
I didn't check that carefully.
You may check the logcat to see what happened.

Best regards,
Chih-Wei

I have 2 devices currently : My internal card (Realtek ALC662 rev3) and a Webcam Mic (Logitech C270). I want to switching mic, the internal card have 2 capture devices (front and rear jack) and the webcam have 1 only. Currently all of Android-x86 version I installed so far are using the webcam one (pcmC1D0c) and I want to switch to rear one (pcmC0D0c), but I tried those commands :

setprop hal.audio.in pcmC0D0c
killall audioserver

But it still recognize my webcam mic as input, I tried many apps and it the same. Although logcat even said that pcC1D0c was ignored, it still being the main one.

I really want a way to dynamically switching I/O since a lot of users report about their mic problem can't switch to the input that they want.

Could you show the logcat after killall audioserver?
You may also trace hardware/libaudio/audio_hw.c
in the source tree to see what went wrong.
