Android image no sound problem

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?

Hi there,



you can use the tinycap api to record and tinyplay api to play the music. thanks.


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

Your Android machine is broken and needs to be replaced! :lol:
