dmesg output ^

i use pipewire and with alsamixer i see the speaker and headphones on the same audio card. Is there a way to split this up through pipewire or alsa?

Re: ALC285 how to split headphones and speakers?

You can pass the indep_hp = true codec hint and reconfigure the HDA codec: https://docs.kernel.org/sound/hd-audio/ … nt-strings and https://docs.kernel.org/sound/hd-audio/ … figuration

This will logically split them if possible, this will bite itself with pipewire's default device detection/setup and you'll either need to write a custom profile or use direct HW access via the Pro Audio profile.

Note for testing/the reconfigure command to work you'll have to stop everything using the audio devices, i.e. 

systemctl --user mask pipewire wireplumber --now

run the reconfigure command and use unmask to reenable them.

See also this thread chain where I helped someone configure this: https://www.reddit.com/r/archlinux/comm … &context=3

Re: ALC285 how to split headphones and speakers?

Check/post aplay -l you should have two distinct output devices - assuming you configured it correctly. Throw in 

amixer -c1
cat /sys/class/sound/hwC*D*/hints

if the indices between your original dmesg are still the same you will have needed to configure hwC1D0

there are two sliders in alsamixer before and now. but what is want is pipewire to split the speakers and headphones so they can have seperate audio playing



can i have a template pipewire conf where i can do this?

Re: ALC285 how to split headphones and speakers?

You can't have "seperate audio playing" if you do not have seperate PCMs, the best you'll get is the same output out of both speakers and headphones if you disable the Auto-Mute Mode control, unless you get the PCM split for which we'd need to see aplay -l. After setting the indep_hp = true hint and running reconfgure what do you get from aplay -l ? If you get seperate devices from that  *then* you can look into altering pipewire, where the easiest way to test this would be to just switch to the 'Pro Audio' profile which will expose all ports and sinks as applicable (but this will still only work like you intend if you can split them at the codec level)

Did you just write the indep_hp = true to the file and did not yet run/write into the reconfigure file? From the state you posted above you need to 

systemctl --user mask pipewire pipewire-pulse wireplumber --now
echo 1 | sudo tee /sys/class/sound/hwC1D0/reconfig
sleep 5
systemctl --user unmask pipewire pipewire-pulse wireplumber --now
#Check aplay and pipewire/pulse states
aplay -l
pactl list cards

Re: ALC285 how to split headphones and speakers?

And this isn't Windows, under windows you have a GUI checkbox you/the Windows realtek driver will have ticked to enable support for this. If you run the sequence of commands I posted what are the outputs you get?

If that is copy/paste from your terminal, then the name is wrong. It should be indep_hp with a "P", not an "X".

Re: ALC285 how to split headphones and speakers?

So the indep_hp adjustment seems to have worked, what do you get from 

speaker-test -Dhw:1,0 -c2
speaker-test -Dhw:1,2 -c2

respectively? If these work, switching to the Pro profile should expose both of them directly.
