Hi All,

there are new versions for all platforms below.  This is mainly a test of an improved build process but does contain a few tweaks, all sdrplay radios should be supported and the windows and mac versions should be more accessible.

Please report any issues.

Sorry Mac users, it look like I got something wrong and the published version does not run.

Hopefully these will work, I have no means of testing the arm version so please let me know if it works

Alan, have you given any thought to my request to be able to turn off or at least minimise the waterfall display?
It is only displaying it that is the problem for me, the processing time is not a problem- there just isn't enough vertical space on a 16.9 monitor to see it all.
I have four virtual receivers set up for 40, 20, 15 & 10 sstv (see links in sig. below), but only three are visible at any one time- removal of the waterfall displays would enable all four spectrum displays to be seen at once, which would be a great help to me in keeping an eye on what is going on on my system.

Hi Alan,

It does not run on either of my M series Macs. Just a brief flash then quits. The non-ARM version immediately fails the same way.

It seems to work fine here. Thanks, Dan

I to would like to have the waterfall out of the way.  As a blind person I don't need that functionality if someone does they should be able to pop it up.

Version 2.0.986 does install on Ubuntu 24.04.1 on Raspberry Pi 5, where previous versions do not. 
However, audio is choppy on any of the audio devices that work.
The HDMI device does not work and selecting it sometimes causes it to disappear. A restart of the computer is necessary to restore it.
None of the other SDR applications I have installed have this problem.

It worked well on Raspberry Pi OS Bookworm.

I tested Version 2.0.986 on my Raspberry Pi 4 running Raspberry Pi OS Bookworm and Pipewire.
The first time I run SparkSDR after a reboot, audio is garbled. It sounds like a fluttering sound or a rapid chop.
If I quit and run SparkSDR again, it sounds fine.
This is very repeatable.

The Ubuntu 24.04.1 system on Raspberry Pi 5 also had pipewire.

DietPi  Bookworm without Pipewire sounded OK with the default audio device or Pulse. However, there are occasional loud popping noises.
The HDMI device works.
It works the first time after a reboot.

Hi, Thanks for the report, I'll try and reproduce it here.  Does turning off the audio resampler make any difference when it goes wrong?

Hi Ken and Justin and all,
hiding either or both of the waterfall and spectrum display is on the list.  First of all I want to get this to a state where it is released as the new stable build, so fix audio issues, some accessibility issues and a few other outstanding bugs. Once this is done I'll get back to adding features, I should have more time as my son is off to university and the sailing season is coming to and end.  The new build setup that consumed most of my efforts recently should speed things up.

I usually turn audio resampler off, so I think that it doesn't make any difference.
Just to be sure, I will try it again when I get back into town Monday or Tuesday.

With Ubuntu 24.04.1 on Raspberry Pi 5, audio resampler makes no difference in the audio quality.
I have never experienced any difference with audio resampler.

Hi, I'd be interested in feedback for this version on rpi to see if it fixes audio issues some people are having.

There is little improvement with version .2.0.988.

On DietPi, the default device and pulse do not work. hdmi works and sounds good.

On Ubuntu 24.04.1, the default and pulse devices are garbled and choppy. hdmi does not work.

Raspberry Pi OS works on hdmi and sounds good. pulse does not work. hdmi not work when I switch back to it.
SparkSDR hangs when I try to close it.
If pulse was previously selected, it will work when SparkSDR is killed and rerun. At this point, hdmi does not work nor does pulse when selected.
The same happens to the default device.
Another time, I ran SarkSDR with hdmi selected and it didn't work, but pulse worked when I selected it.
It's hard to see a pattern here.

Another common ground between Ubuntu and Raspberry Pi OS is pipewire. Not on DietPi.

I just heard about SparkSDR and I thought I'd give it a try on my Radxa 5A Octacore Arm64 SBC but I find it has a stutter problem with a SDRplay RSPdx. It's not constant but annoying. Is there a audio sample rate setting somewhere? I'm using a Cublix CB5 usb audio adapter which is capable of 192kHz in/out. I watched a Youtube video where WE6Z was using SparkSDR with the same Cublix usb adapter but under Windows a year ago. I'm using Debian 11 bullseye, 16GB memory, kernel: Linux rock-5a 5.10.110-29-rockchip.

Note: On the the same SBC I have CubicSDR, SDR++, SDRangle, and SDRConnect preview 4 which have no stutter problems.

Hi,
A number of people have reported audio issues recently. It is worth checking the cpu usage just to check if that is unusually high.  Do you know if pipewire is being used?

If you are using Pipewire, there are issues. If so...

There is a test version that uses pipewire directly

No, pipewire wasn't being used just Alsa and Pulse audio. So I tried it with pipewire and there was no change other than the volume level was a little higher so I reverted back to Pulse/Alsa. The cpu usage was about the same as the other sdr programs, that is 85%-90% cpu usage on all eight cores. My description of the auto was misleading. It's not stuttering but rather there are audio dropouts occasionally about every 5 seconds. Seems like there's a buffering problem.

Do you have a 2.0.990.linux-x64 version to test for choppy audio?

Hi Jim,
I did all the dev work for the pipewire version on x64 so it does exist but I'm just trying to incorporate it into the standard version so it tries pipewide and falls back to portaudio if no there, hopefully I'll release it sometime next week.

Alan,

FYI:
I built a version of Armbian/Debian Bookworm with a version 6 kernel: Linux rock-5a 6.11.2-current-rockchip-rk3588 #1 SMP PREEMPT Fri Oct  4 09:38:57 CDT 2024 aarch64 GNU/Linux with Cinnamon Desktop I reinstalled SDR++, CubicSDR, SDRangle, SDRconnect and SparkSDR for use with the SDRplay RSPdx. I only tested them with FM/FM Stereo stations and they all work with the OS. However, SparkSDR doesn't sound right with stereo. Mono FM is fine. It's almost like the old analog radios when the stereo 19kHz pilot signal wasn't locking in the phase-lock loop detector. I also had to use something else for the audio device besides default or pulse such as upmix or vdownmix to prevent the audio dropouts.
