Hello, I'm running FreeBSD 12.1 release host with the HD bhyve audio patch from 13-current. On a OpenSUSE 15.2 bhyve guest, audio works perfectly fine. However, on FreeBSD 12.1 only noise comes out. Using /dev/dsp4 (which is a USB sound device), audio works fine, but not on /dev/dsp0, the default sound device on my system. I see the following relevant errors: pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout, channel dead pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout, channel dead pin dump from FreeBSD 12.1 VM. ------------------------------ hdaa0: Dumping AFG pins: hdaa0: nid 0x as seq device conn jack loc color misc hdaa0: 3 00001010 1 0 Line-out Jack Unknown 0x00 Black 0 hdaa0: Caps: OUT Sense: 0x80000000 (connected) hdaa0: 5 00805020 2 0 Line-in Jack Unknown 0x00 Red 0 hdaa0: Caps: IN Sense: 0x80000000 (connected) hdaa0: NumGPIO=0 NumGPO=0 NumGPI=0 GPIWake=0 GPIUnsol=0 I tried sysctl dev.hdac.0.polling=1 with no success. Note that: The above problem is also reproducible on 13-Current 20200917. Any help is appreciated. Kind regards, Ali
