might be helpful cross-posted from: https://lemmy.ml/post/9547307

so since I digged pretty hard to find what is a ucm profile and how to seperate headphones from speakers in pipewire and alsa so yeah heres a guide first of all these are my sources:

https://github.com/luisbocanegra/linux-guide-split-audio-ports https://www.reactivated.net/writing_udev_rules.html https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/3556 https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/3552

you need a custom ucm profile use this command since its helpful lspci -nn -vvv

SUBSYSTEM!="sound", GOTO="pipewire_end"
ACTION!="change", GOTO="pipewire_end"
KERNEL!="card*", GOTO="pipewire_end"

ATTRS{subsystem_vendor}=="0x103c", ATTRS{subsystem_device}=="0x8742", ENV{ACP_PROFILE_SET}="custom.conf"

LABEL="pipewire_end"

and than create a file in /usr/share/alsa-card-profile/mixer/profile-sets/custom.conf and yeah I guess

https://www.freedesktop.org/wiki/Software/PulseAudio/Backends/ALSA/Profiles/

and this especially

https://github.com/luisbocanegra/linux-guide-split-audio-ports

they helped a lot

.include 9999-custom.conf

and yes that was my custom.conf and yes just reboot now and you are set btw no need to touch hdajackretask and that idor 0,2 and 0,0 I just switched profile to proaudio and than ran pactl list sinks short and took the ids from there I am basically following the guides and mimicking /usr/share/alsa-card-profile/mixer/profile-sets/default.conf to be completely honest yes thats all

      two different outputs one is speaker one is your headphone jack this gives you the power for exemple to play different audio in your speaker and headphones at the same time using qpwgraph for exemple

        Ah ok, probably because of laptop, but built-in speakers and headphones are already differentiated for me.
