I have a problem with the sound on my workstation. It works fine immediately
after booting and then stops. Dmesg shows this:
[root@vhost01 ~ (master)]# dmesg | grep pcm
pcm0: <NVIDIA (0x0051) (HDMI/DP 8ch)> at nid 4 on hdaa0
pcm1: <NVIDIA (0x0051) (HDMI/DP 8ch)> at nid 5 on hdaa0
pcm2: <Realtek ALC892 (Rear Analog 5.1/2.0)> at nid 20,22,21 and 24,26 on hdaa1
pcm3: <Realtek ALC892 (Front Analog)> at nid 27 and 25 on hdaa1
pcm4: <Realtek ALC892 (Rear Digital)> at nid 30 on hdaa1
pcm2: chn_write(): pcm2:virtual:dsp2.vp1: play interrupt timeout, channel dead
pcm0: <NVIDIA (0x0051) (HDMI/DP 8ch)> at nid 4 on hdaa0
pcm1: <NVIDIA (0x0051) (HDMI/DP 8ch)> at nid 5 on hdaa0
pcm2: <Realtek ALC892 (Rear Analog 5.1/2.0)> at nid 20,22,21 and 24,26 on hdaa1
pcm3: <Realtek ALC892 (Front Analog)> at nid 27 and 25 on hdaa1
pcm4: <Realtek ALC892 (Rear Digital)> at nid 30 on hdaa1
The dead channel corresponds to the audio jack on the back of the system into
which my speakers are plugged. It also corresponds to the contents of
/dev/sndstat
cat /dev/sndstat
Installed devices:
pcm0: <NVIDIA (0x0051) (HDMI/DP 8ch)> (play)
pcm1: <NVIDIA (0x0051) (HDMI/DP 8ch)> (play)
pcm2: <Realtek ALC892 (Rear Analog 5.1/2.0)> (play/rec) default
pcm3: <Realtek ALC892 (Front Analog)> (play/rec)
pcm4: <Realtek ALC892 (Rear Digital)> (play)
No devices installed from userspace.
>From my research this appears to be a recurrent bug but I cannot make any of
the suggested remedies work. Any assistance with this is greatly appreciated.
