Laptop audio output devices missing

English Hardware

Hello all,

I’m a new Linux user and have been trying Opensuse Tumbleweed for the past few weeks and as a whole I am enjoying the experience, although I have a few problems that I’ve been unable to solve. The most frustrating issue is with audio output devices. I assume the problem is related to another users issue, but I see no fix.

If I have a HDMI cable inserted, I can get output via HDMI. If I remove the HDMI cable, no audio devices will show until I run : sudo udevadm trigger. Then my laptop speakers (and headphone port) will show.

If I were to then re-insert the HDMI cable, it will not show as an output device until I run: systemctl --user restart pipewire. However, this will cause the laptop speakers to no longer show.

Restarting my laptop makes no difference.

When I unplug HDMI (no laptop speakers) and run: speaker-test -Dplug:front -c2 -l5 -twav - sound is played from laptop speakers. No sound is played when running: play -vv /usr/share/sounds/alsa/Front_*. With the following output:

If you try removing ~/.cache/gstreamer-1.0/registry.x86_64.bin (as per the bug report), then log out and back in, does the sound output behaviour remain?

Others reported that if a new user login is created, the problem is not observed for that account. Is this the case for you?

Thanks for your response.

I’ve tried removing registry.x86_64.bin and now I can get both laptop speakers and HDMI output to show, but only by changing the audio profile between analogue (for laptop speakers) and digital for the HDMI. Is this normal behaviour? If I have the profile set to digital when I remove the HDMI, I do not have the option to change the audio profile to analogue.

The audio profile/output does not automatically change on connecting/disconnecting HDMI. Is this normal? Is there a way to automate the change? I have tried loading the module-switch-on-connect module as per here (the always sink module was already loaded).

I only ever have one audio sink showing run I run wpctl status:

  • With digital audio profile selected:

Upon disconnecting HDMI, the laptop speakers momentarily show before disappearing. See screen recording.

Sorry, I just noticed the post by user MrTHXcertified.

I’ve tried removing ~/.local/state/wireplumber and restarting the service with no changtes to behaviour.

My output for pactl list cards:
