To be clear,... It is not a Playback problem, it is a rendering problem,
for the audio, web format.
For Info, in Preferences->Settings->Playback my setting is: Alsa,
default, 16bit.
In my project file there are two Audio tracks on Timeline (Left+Right).
The source audio file is a stereo WAV file.
The link to hear the scratches: https://files.fm/u/ux748j3zwz
It is strange. For the MOV preset the audio is Okay. I will try to go
back in time with the versions I saved on my Hard Disk.
My tests using:
- cin-x86_64_older_20240421.AppImage (audio scratches)
- CinGG-20240229-x86_64-older_distros.AppImage (audio scratches)
- CinGG-20221031-x86_64-older_distros.AppImage (audio scratches)
- cinelerra-5.1-ub16.04-20201031.x86_64-static (OKAY)
=====================

IgorBeg, in Preferences/Settings/Playback A what is the audio set
to? The default on a new startup seems to be Alsa, default, 16
bit linear. Unfortunately I have no speakers on my Ubuntu 16 O/S,
but when I download this new AppImage and load a ffmpeg 7.0 audio
filter on my laptop, it works for me. I am confused by your bad
results. Also, even though you get those error messages, are you
getting audio because you say it is "scratchy", so it is working?
If you set encoding preference to add newly encoded asset to new
tracks you can easily see for default webm profile (at least on slower
machine?) that resulting audio waveform is very glitchy and different
from source audio....

AppImage for my old UbuntuStudio.
Same messages and issues as before for me by my tests.
CLI output:
FFStream::encode_frame: encode failed.
file:
/home/charlie/Documents/temp/pippo_ffmpeg7_test-20240421-2.webm
err: Resource temporarily unavailable
FFMPEG::mux_audio err: Operation not permitted
And the audio of the rendered file is full of scratches,
unfortunately.
