Android image no sound problem

Post by nikolay.skudnyakov » Wed Oct 24, 2018 6:26 pm

Can you please help us deal with the sound problem. We've tried all audio options in settings, plugged in headphones, but there is no sound.

Here is the log:

Ok, i went through the process, and i'm able to record and play audio (and everything works), but in the android apps there is no sound, how to deal with that?

And you can give a link to the source code for the image of Android, which is available for download. Just maybe I'll try to rebuild with the other settings, but I need a driver assembly
