Hi

I have install android x86 on hard disc.

I can't listen to the audio. There isn't the volume icon.

Somebody else had the same problem ?

Search the forum for audio output issues. There are plenty of threads with sound advice.

I'm not an expert, but this output on your logcat:

04-14 15:52:54.750 1644 1644 W WiredAccessoryManager: This kernel does not have usb audio support
04-14 15:52:54.750 1644 1644 W WiredAccessoryManager: This kernel does not have HDMI audio support

Says you don't have audio support, but if you see, on mine it recognizes my outputs, see the difference:

02-23 20:34:59.309 1475 1475 D audio_hw_primary: found audio out at /dev/snd/pcmC1D10p

It founds audio!!! Maybe it's some hardware incompatibility, or... are you using another kernel? I'm using stock lineageOS r1 from android-x86 site.
