[BUG] HP Omnibook Ultra Flip: sound from speakers when headphones plugged in

[qwence]

Describe the bug
When I plug my headphones (connected via normal headphone jack) into my HP Omnibook Ultra Flip 14 laptop (which uses a Lunar Lake chip), sound comes out of the speakers as well as the headphones. I'm using pipewire-pulse and alsa, and alsamixer shows that the speakers are muted when the headphones are plugged in. pavucontrol shows that the output switches from speakers to headphones. This works as expected on windows, and also the headphones work fine on my other linux laptop.

Reproduction Rate
It happens every time.

Expected behavior
When headphones are plugged in, sound comes out of the headphones but not the speakers.

Adding @ujfalusi who has recently solved a similar issue with HDA spk/hp switch. @qwence this is a userspace issue, where the UCM configuration is not muting the speaker via alsamixer (you should be able to manually mute in alsamixer for the time being)

[qwence]

When I plug in headphones, alsamixer already reports the speaker as muted.

@ujfalusi Let me know if you have any ideas, or if there is a more appropriate place for me to report this (I wasn't sure).

[ujfalusi]

@qwence, the first thing we ask is to confirm the behavior with the legacy HDA stack by adding
options snd_intel_dspcfg dsp_driver=1 to for example /etc/modprobe.d/force-legacy-hda.conf and reboot
You will loose DMIC, but you should be able to verify the Speaker/Headphone issue.

Have you tried to manually change the mixer controls (alsamixer -c0) while playing audio and having the headset connected?
Is there a combination when the audio is routed correctly?

It looks like the device needs some quirk to get it's configuration right.

Can you also share the output of amixer -c0 contents and amixer -c0 scontents ?

@KailangYang Could you help on it?

[ujfalusi]

One thing that is interesting in alsa-info is that it presents two Jack function ('Mic Jack' and 'Headphone Jack') while the laptop has a single combination jack for headphone/headset/mic, likely unrelated to the speaker is always on issue, but hints of mis-identification of the setup.

I tried the legacy HDA stack as suggested and it resulted in the same behavior.

When I do alsamixer -c0 with the headphones plugged in, it shows the speaker as muted. I can use the gui to unmute the speaker, change the volume to zero, and remute it, and none of this changes the sound coming out of the speakers. I also tried changing the other settings and they don't affect the problem; various settings will raise/lower the volume, and they affect both the headphone sound and the unwanted speaker sound.

One other observation is that the speaker sound does change when the headphones are plugged in: it is less loud, but also different in quality-- less full or less bass? (Sorry, I'm the exact opposite of an audiophile.) I wonder if there are multiple speakers and only one is muted. (alsamixer does only show one entry for "speaker".)
