Hi!
I need help with my headset, it's a Logitech G Pro X Headset. I've tried to enable surround sound in alsamixer, like unmute the LFE channel and surround channel, but that has gotten me nowhere.
I hope someone can help with this.

aplay -lL
amixer -c0 #or whatever the card index of the headset is

Note that many of these headsets do not actually have surround capable speakers but emulate it in software, but post these outputs so we can actually verify what's up

Sorry I was out traveling for a few days, that was not very convenient.

That's just the last output which is the least interesting for determining whether you have any actually exposed 7.1 capabilities. You should post all of them

I think the card index is 1, thats where i found the LFE and Surround channels. Although there is a sound card named "Pro X", but it only has the PCM channel.
Offline
The card index is 3 (the last card in the aplay output) simply going by PCMs it does expose 7.1. Without anything else playing, do you get all speakers from
speaker-test -Dsurround71:CARD=X,DEV=0 -c 8
(you should hear white noise on all channels)
What does indeed not happen is that pulse/pipewire exposes all of them but this just reads like an ACP bug with the gaming headset preset, and should be relevantly fixable. I'm not at home right now but you could technically configure that in /usr/share/alsa-card-profile I'm assuming it uses one of the gaming profiles and these don't have relevant mappings for the surround support yet. You can look around there and check whether you grok the config format to expose these properly, otherwise I'll be on my PC later this evening and might be able to help writing a proper definition.

When running the speaker-test command, I get an error.

Broken configuration for playback: no configurations available: Invalid argument
Setting of hwparams failed: Invalid argument
I appreciate the help with writing the definition, I'm not very good at configuring sound.

A so this is actually bugged anyway... does surround51 instead of surround71 work correctly? so
speaker-test -Dsurround51:CARD=X,DEV=0 -c 6
? Output of
lsusb -vd 046d:0aaa
?

Surround 5.1 doesn't work either.

Mhmmhm... Then this might indeed be broken, does the digital profile work
pactl set-card-profile alsa_card.usb-Logitech_PRO_X_000000000000-00 output:iec958-ac3-surround-51+input:mono-fallback
though if I'm interpreting that lsusb correctly then the "surrround channels" aren't actually exposed at all.

It does do something, it produces a very loud sutter sound, and that's just it.
But I can see the 5.1 channels in the System Settings in the Audio page.
