Strange behaviour of sound oputput

I observe strange audio behavior on my laptop with a fresh installation of Arch with Plasma 6.
The internal speaker and HDMI outputs are mutually exclusive: when the monitor is connected to HDMI this is the only available output and the internal speakers are not visible in the controls, however they become available again when the monitor is disconnected.
With other installations I have always had the possibility to choose the audio output, in this case not. This is an annoying problem as the monitor in the office has no speakers and Linux forces me to redirect the output to it.
Fortunately, bluetooth headphones can be selected once connected.
This is the sound card model:

00:1f.3 Multimedia audio controller: Intel Corporation Tiger Lake-LP Smart Sound Technology Audio Controller (rev 20)

Do you know what to investigate to resolve?

Re: Strange behaviour of sound oputput

You should very likely have a switchable profile for this, but since there's not much concrete data what do you get from 

aplay -lL
pactl list cards
pactl list sinks
sudo dmesg | grep -E 'snd|sof'

FWIW should the above not be fruitful, there's actually a new kernel parameter since 6.7 to disable the GPU from binding to the audio interface. Try adding 

snd_hda_core.gpu_bind=0

to your kernel parameters: https://wiki.archlinux.org/title/Kernel_parameters

Re: Strange behaviour of sound oputput

Sorry, I posted the results from a different laptop so I have to delete. I will collect data from the right PC soon.

Re: Strange behaviour of sound oputput

You properly get exposed all of the sinks, you should be able to move all audio to the headphones/or "speaker" sink with pavucontrol and similar tools.  unless headphone and speaker is the differentiating factor in which case you can switch between the two with 

pactl set-card-profile alsa_card.pci-0000_00_1f.3-platform-skl_hda_dsp_generic "HiFi (HDMI1, HDMI2, HDMI3, Mic1, Mic2, Speaker)" #That this is actually the qualifying name is pretty stupid I agree, but that's what you get with UCM configuration for some reason.
#or alternatively
pactl set-card-profile alsa_card.pci-0000_00_1f.3-platform-skl_hda_dsp_generic "HiFi (HDMI1, HDMI2, HDMI3, Headphones, Mic1, Mic2)"

Re: Strange behaviour of sound oputput

I have the same issue for a few weeks now, and I noticed that the output sink is changed when a monitor is connected by HDMI.

With no external monitor:

$ pactl list short
(...)
1398    alsa_output.pci-0000_00_1f.3-platform-skl_hda_dsp_generic.HiFi__HDMI3__sink     PipeWire        s24-32le 2ch 48000Hz    SUSPENDED
1399    alsa_output.pci-0000_00_1f.3-platform-skl_hda_dsp_generic.HiFi__HDMI2__sink     PipeWire        s24-32le 2ch 48000Hz    SUSPENDED
1400    alsa_output.pci-0000_00_1f.3-platform-skl_hda_dsp_generic.HiFi__HDMI1__sink     PipeWire        s24-32le 2ch 48000Hz    SUSPENDED
1401    alsa_output.pci-0000_00_1f.3-platform-skl_hda_dsp_generic.HiFi__Speaker__sink   PipeWire        s32le 2ch 48000Hz       SUSPENDED
(...)

After plugging in an external monitor:

$ pactl list short
(...)
1333    alsa_output.pci-0000_00_1f.3-platform-skl_hda_dsp_generic.HiFi__HDMI3__sink     PipeWire        s24-32le 2ch 48000Hz    SUSPENDED
1334    alsa_output.pci-0000_00_1f.3-platform-skl_hda_dsp_generic.HiFi__HDMI2__sink     PipeWire        s24-32le 2ch 48000Hz    SUSPENDED
1335    alsa_output.pci-0000_00_1f.3-platform-skl_hda_dsp_generic.HiFi__HDMI1__sink     PipeWire        s24-32le 2ch 48000Hz    SUSPENDED
1336    alsa_output.pci-0000_00_1f.3-platform-skl_hda_dsp_generic.HiFi__Headphones__sink        PipeWire        s32le 2ch 48000Hz       SUSPENDED
(...)

For some reason the output sink changes from `Speaker` to `Headphones`, I suspect the same is happening for rootkit?

Anyways, the command listed by V1del fixes this issue!!

Re: Strange behaviour of sound oputput

Same problem happening to me on HP ProBook 450 G9. I can also confirm that the command V1del posted is a temporary fix for this issue.
