I've searched extensively through existing resources, many of them have every single symptom presented by my system, but their solutions are not working for me.

This user has had a similar experience: PulseAudio has no sound, only has Dummy Output

I ran into all of the suggested solutions he also has, and tried them one by one.

Previously I was running an 1660Ti, no problem having both HDMI/DP sound and mobo sound simultaneously. I've since then upgraded to a 3070 and from there I have not had mobo sound.

Finally, I tried the answer suggested on the linked question - https://askubuntu.com/a/1359089 - it does correctly set my mobo card as default, however it just shows as Dummy Output.

I have made sure I have all the required modules in my kernel as suggested here: Only "Dummy output" (sound) in Ubuntu 20.04 after reboot - Broken driver / module

I've also tried downgrading to a previous kernel version.

Although I didn´t fiddle with them, I tried loading live versions of Ubuntu and Fedora, but both had the same problem.

One thing to note, I'm running Pop!_OS 22.04 but I'm posting here given the lack of a good Pop!_OS community for support.

  • I plugged back the 1660ti and still no sound. Could my sound card have fried at some point when switching GPUs? – João Sep 12 '23 at 04:43

Your headphones are probably on mute, that is why they are not showing

you can try going on alsamixer and unmuting

  • hi. I had gone through this before, seems that every now and then it resets to mute, but still no changes when unmuting and rebooting – João Sep 12 '23 at 01:51
