Sound Issue

[Rainer Dorsch]

Hi,

sound was working for years on my Debian System w/o any issue with pulseaudio. 
Since a few weeks I have problems with the on-board Intel sound, listed as

Device-1: Intel Cannon Lake PCH cAVS driver: snd_hda_intel 

whereas the Logitech USB headset always works

Device-2: Logitech Headset H390 type: USB driver: hid-generic,snd-usb-
audio,usbhid 

Full inxi -F output is here:

Out of the blue I noticed today that it worked again, but after I rebooted 
into Debian 10.8 it disappeared again.

In dmesg I find

In $ pactl list I get

but there is no other sound card listed.

I tried from the Debian pulseaudio wiki the part under "Missing playback 
devices or audio capture":

rd at h370:~$ rm -r ~/.config/pulse /tmp/pulse-*
rm: cannot remove '/home/rd/.config/pulse': No such file or directory
rm: descend into write-protected directory '/tmp/pulse-PKdhtXMmr18n'? y
rm: remove write-protected directory '/tmp/pulse-PKdhtXMmr18n'? y
rm: cannot remove '/tmp/pulse-PKdhtXMmr18n': Operation not permitted
rd at h370:~$ ls -ld /tmp/pulse-PKdhtXMmr18n
drwx------ 2 root root 4096 Feb  6 20:19 /tmp/pulse-PKdhtXMmr18n
rd at h370:~$ systemctl --user restart pulseaudio.service
rd at h370:~$ 

Not sure if it is expected that there is a pulse file for root in /tmp

What is also strange for me, is that the intel card is listed by-path by not 
by-id:

rd at h370:~$ ls -l /dev/snd/by-id/                                     
total 0
lrwxrwxrwx 1 root root 12 Feb  6 20:42 usb-Logitech_Logitech_USB_Headset-00 -> 
../controlC1
rd at h370:~$ ls -l /dev/snd/by-path/
total 0
lrwxrwxrwx 1 root root 12 Feb  6 20:42 pci-0000:00:14.0-usb-0:13.1:1.0 -> ../

lrwxrwxrwx 1 root root 12 Feb  6 20:19 pci-0000:00:1f.3 -> ../controlC0
rd at h370:~$ lspci |grep 00:1f.3
00:1f.3 Audio device: Intel Corporation Cannon Lake PCH cAVS (rev 10)
rd at h370:~$ 

Any idea or hint how to debug this issue is welcome.

Many thanks
Rainer
