Sound has Disappeared.

Another possibility is to use powered headphones which these days can be quite decent for as low as 20 bucks. -- Behringer Powered Headphones --. I prefer using an actual Home Theater type Receiver/Audio Center but powered headphones ain't too shabby these days.

Here's a sample of modern Sony A/V Receivers at various price ranges. -- Some Modern Sony Receivers ---

Edit: oops. The original page showed me 5 different Sony A/V receivers starting at under 200 bucks but now all i see is one I like at more than twice that. It is really worthwhile though to look at the photo of the back panel to see all the modern connectors and options.

If you can route the audio via HDMI to the monitor and the monitor has speakers, said monitor will most likely have a headphone jack as well. A while back this is how I did it to permanently route audio to a 1080p TV; pre-pulseaudio 14.1. I then used the TV speakers or plugged in wireless headphones.

Code:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 7: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 8: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 9: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

The audio was on card 0, device 9, so then edit .asoundrc (or /etc/asound.conf)

Code:

pcm.!default {
  type plug
  slave.pcm "dmixed"
}

pcm.dmixed {
  type asym
  playback.pcm {
    type dmix

    ipc_key 5678293
    ipc_perm 0660
    ipc_gid audio
  
    slave {
      channels 2
      pcm {
        type hw
        card 0
        device 9
      }
    
      period_size 1024
      buffer_size 8192
    }
    bindings {
      0 0
      1 1
    }

  }   
  capture.pcm "hw:0"
}

@kingbeowulf,
Many thanks for the suggestion, but, unfortunately, the monitor doesn't have output jacks of any kind.

Ok lets confirm the many places where either muting can occur or config "wrong" can occur

pls post the contents to these files...if not found say so please

Quote:

/etc/asound.conf (systemn wide config)
~.asoundrc (home user config)

are you using system wide pulse configs found at /etc/pulse or
home user found at .config/pulse?

take a screenshot of (the default command shows output only)

Code:

alsamixer -c0

if the wrong device is showing up, say so
then see if you can take a screenshot of the correct device if it can found in that last command by pressing F6

2) if you know how to take a snippet of log....show the snippets for all hardware for sound for a recent boot please.

3) have you changed any setting in /etc/modprobe.d?

4) now run pavucontrol

post a timed screenshot of the pulldowns in the config tab for the various devices available as seen by pulseaudio (PA)
if PA sees only hdmi just say so

^ so this example would show SPDIF has been selected which is not what you want.

According with the OP, the built-in audio is dead. Physically dead. Broken. Not working anymore.

Also, to note that he's NOT a rookie, then I trust him about diagnostics.

Then, no software Voodoo would help...

Put in a ten Dollar USB "sound card" and plugged in the headphones. That works, but "solving the problem" would require a new motherboard.
I'll think I'll wait until the dust settles regarding the new Ryzen chips and Linux support for the same.
