Completely broken audio in 20.08.1. Realtek ALC892.

Post by CoatlessEskimo »

I have made sure the sound driver is properly loaded. "cat /dev/sndstat" gives the following output:

Code: Select all

Installed devices:
pcm0: <ATI R6xx (HDMI)> (play)
pcm1: <ATI R6xx (HDMI)> (play)
pcm2: <ATI R6xx (HDMI)> (play)
pcm3: <ATI R6xx (HDMI)> (play)
pcm4: <ATI R6xx (HDMI)> (play)
pcm5: <ATI R6xx (HDMI)> (play)
pcm6: <Realtek ALC892 (Analog 8ch/2.0)> (play/rec)
pcm7: <Realtek ALC892 (Front Analog)> (play/rec) default
pcm8: <Realtek ALC892 (Rear Digital)> (play)
pcm9: <USB audio> (rec)
No devices installed from userspace.
I have tried manually setting the DSP device with "sysctl hw.snd.default_unit=X", with 'X' being the numbers 6 through 8. I want output through the front analog audio jack, and none of the jacks have worked with any default sound devices I've set. I have also tried using the MATE method of setting the default audio output. Also worth note is that when using /dev/dsp6-8, audacity crashes after trying to play a file. They seem to play correctly through the HDMI outputs. What can I do to resolve this problem?

Looking around for more details to post a better setup your sound ... em-to-work Some information may be helpful

this sound chip is Intel HDA, but should work with debugging your Realtek Chip.
