[Dell XPS 15 9560] Pipewire correctly detects laptop sound & speakers but no sound

[Luis Alberto Pabón]

Every now and then, after boot, I get no sounds at all coming from the speakers. Everything seems normal - the control center reports the output as active, and if I play anything with sound I can see the VU meter going back and forth. I've attached a screenshot showing as much.

The internal microphone does not pick up any sounds either when this happens.

If I connect my Bose NC700 bluetooth headset, I get sound out of it just fine, and the mike on it also works.

Sometimes the internal sound will start working after a few times of switching back and forth internal audio / bluetooth headset.

Restarting the systemd pipewire and pipewire-pulse user services doesn't help. Nor does killing & respawning wireplumber.

Extra info: this happened on this same laptop on an old install (upgraded from Ubuntu 19.10 all the way). I reinstalled 22.04 yesterday from scratch with ZFS root and upgraded to 22.10 (the latter installer did not let me create a ZFS root with encryption).

Cheers Daniel, I'll do so the next time this issue happens.

[Luis Alberto Pabón (copong)]

I could actually reproduce it straight away after a cold boot. Attached.

It looks like ALSA (the kernel) needs some tweaking because it is reporting "speaker_outs=0"

That does sound like it could be an issue for sure.

Ah my apologies, I didn't realise I had already reported this a few months back when updating to jammy here https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1965750
