No Sound After Update and pkg upgrade

B

I upgraded from 13.0-RELEASE p1 to p3 and then did pkg upgrade which bumped nvidia-driver from 460.67 to 460.84. Afterwards I can't get sound from my speakers (connected from the monitor), even with cat /dev/urandom > dsp0 , and of course trying the other dsp1, dsp2, and dsp3. Here's what I've checked thus far:

Code: 
root@dom0:~ # dmesg | grep pcm
pcm0: <NVIDIA (0x0092) (HDMI/DP 8ch)> at nid 4 on hdaa0
pcm1: <NVIDIA (0x0092) (HDMI/DP 8ch)> at nid 5 on hdaa0
pcm2: <NVIDIA (0x0092) (HDMI/DP 8ch)> at nid 6 on hdaa0
pcm3: <NVIDIA (0x0092) (HDMI/DP 8ch)> at nid 7 on hdaa0

root@dom0:~ # kldload snd_hda
kldload: can't load snd_hda: module already loaded or in kernel

root@dom0:~ # cat /dev/sndstat
FreeBSD Audio Driver (64bit 2009061500/amd64)
Installed devices:
pcm0: <NVIDIA (0x0092) (HDMI/DP 8ch)> on hdaa0  (1p:1v/0r:0v) default
pcm1: <NVIDIA (0x0092) (HDMI/DP 8ch)> on hdaa0  (1p:1v/0r:0v)
pcm2: <NVIDIA (0x0092) (HDMI/DP 8ch)> on hdaa0  (1p:1v/0r:0v)
pcm3: <NVIDIA (0x0092) (HDMI/DP 8ch)> on hdaa0  (1p:1v/0r:0v)
No devices installed from userspace.

root@dom0:~ # mixer
Mixer vol      is currently set to 100:100
Mixer pcm      is currently set to 100:100

So the system sees NVIDIA sound hardware, kernel has drivers loaded, device appears with sndstat, and mixer volume is up. I'm at a loss for what to do/check. I tried rolling back nvidia-driver with: pkg delete nvidia-driver-460.84 and pkg install nvidia-driver-460.67.txz , but I get the error:

Code: 
Proceed with this action? [y/N]: y
[1/1] Installing nvidia-driver-460.67...
pkg: nvidia-driver-460.67 conflicts with libglvnd-1.3.3 (installs files into the same place).  Problematic file: /usr/local/lib/libGLX.so

Any ideas?
 
Thanks. Somehow I spent an hour overlooking the "/dev/" part of the dsp0. That caused sound output, and then somehow that also fixed the problem with no sound coming from the browser.

Could it be that the browser (in a jail) isn't able to create the /dev/dsp device until it is already created with the cat /dev/urandom > /dev/dsp0 from the host? Kinda weird
 
Has anyone tried to change the default sound device/port?
Code: 
# sysctl hw.snd.default_unit=n
where n is 0, 1, 2, or 3?

Also, putting that same hw.snd.default_unit=n into /etc/sysctl.conf would help... all of that info dug up from the FreeBSD Handbook...

Right.

I do use hw.snd.default_auto=2 which switch to the latest connected audio device.

That means if i disconnect my usb device then it switches automatically to the inbuilt soundcard.

/dev/dspX devices aren't 'created at runtime'... If a browser in a jail cannot access them, I would suggest the following troubleshooting list:
  1. Can a browser running outside of a jail access /dev/dspX? If yes, then jail permissions might be the issue to explore. If not, permissions for /dev/dspX might be the issue to look at. Maybe the account that's running the browser does not have proper perms...
  2. Can another jailed app (say, VLC) access the /dev/dspX? If yes, then the issue is most likely the browser app itself. Either re-compile the browser with different flags, or re-install the browser, or upgrade it. If the answer to Question 2 is no, that confirms that jail permissions are definitely the issue to be resolved first. After that, you can look and see if the account running the jail itself can access the /dev/dspX.
