I have followed the instructions to build and install the desktop head unit on a Debian 10.6.0 64bit VM in VMWare.
I connected my Pixel4 phone with Android11 to the desktop head unit, and tied to play some music from the YoutubeMusic.
There was sound output but just the configuration was not correct, either the channels or the sample rate was wrong.
I can see from the log there were some PCM open errors but the sound did played out.
And I tried to look at the source code and the audio config for music audio is 16bit-48kHz-2ch which was right.
So, what else could be going wrong?
Here is the log:
