[SOLVED] Logitech G432 headset surround sound does not work

Installed Arch on a Lenovo ThinkPad T15p yesterday. Everything else appears to work fine, but I can only use my Logitech G432 headset in stereo mode. Its surround sound mode works on Windows (on another laptop), but if I go to KDE system settings and change the headset's profile to "Digital Surround 5.1 (IEC958/AC3) Output", I only hear a very repetitive and painful noise from the headset, regardless of whether sound is actually playing or not.

aplay -l gives:

How can I enable surround sound with this? Do I need any packages? Any tests I can do?

Re: [SOLVED] Logitech G432 headset surround sound does not work

Do you know whether this is actual real surround or just software emulation? Many of these headsets don't really implement that but emulate it in the driver/software. FWIW assuming you aren't playing anything else, what do you get from

speaker-test -Dsurround51:CARD=Headset,DEV=0 -c6

? Do you get audible noise in each channel? What's your output for

amixer -c1
pactl list cards

Edit: https://www.logitechg.com/en-us/product … 00769.html suggests this is just software emulation built into the driver (hover over the 1 superscript on the "surround" feature point...).

You can fake that just the same: https://gitlab.freedesktop.org/pipewire … l-surround e.g. the 5.1 kemar sample needs ssr installed then you should be able to use that to create your own virtual surround implementation. FWIW a googler also turned up e.g. https://www.reddit.com/r/linuxaudio/com … &context=3 which has some links to some more surround files that might give different/better results.

Re: [SOLVED] Logitech G432 headset surround sound does not work

Output of speaker-test:

speaker-test 1.2.8

Playback device is surround51:CARD=Headset,DEV=0
Stream parameters are 48000Hz, S16_LE, 6 channels
Using 16 octaves of pink noise
Broken configuration for playback: no configurations available: Invalid argument
Setting of hwparams failed: Invalid argument 

Looked up some stuff, don't know why it doesn't quite work when it used to. (Edit: Mono/stereo channels work when I do not attempt to reproduce surround sound.) I installed pipewire instead of pulseaudio and rebooted, to the same result.

I will take a look at the links you've posted.

Re: [SOLVED] Logitech G432 headset surround sound does not work

What do you mean "it used to work" ? Did you use that same headset on linux and it worked in a surround configuration? The AC3 profile? these generally need something that encodes your normal PCM stream to AC3 but these are often a hassle to config. From what I'm reading surround here is only a software implementation which makes me not surprised that it wouldn't work.

Apologies for the murky response. I meant that I used to be able to run the speaker-test command without errors on six or eight channels, which I cannot do now, on the same headset. The issue back then was that only the Front Left/Front Right channels would emit sound and the others would be silent and called Unused. Cannot reproduce this now. I am trying to configure virtual surround sound now as well. Will edit with my findings.

Re: [SOLVED] Logitech G432 headset surround sound does not work

speaker-test -Dsurround51 will completely bypass pipewire or pulseaudio and should also not be attempted while either is actively using the device/playing back (... prior to running the speaker-test sudo fuser -v /dev/snd/* should not show a pcm device occupied) but still according to the spec sheet the result while it was working is expected to me, since surround is not actually present and just a faked software impl.

Re: [SOLVED] Logitech G432 headset surround sound does not work

I am glad to report I have succeeded in producing virtual 5.1 surround sound with this setup.

Here is a step-by-step guide, as I recall:

1. Go to https://gitlab.freedesktop.org/pipewire … kemar.conf and download the file; as specified in the header, it should be placed in a directory such as ~/.config/pipewire/filter-chain.conf.d/ . The other subfolder, pipewire.conf.d should also be usable.

2. Go to https://airtable.com/shruimhjdSakUPg2m/ … ZKWJDnLtTc and download a .wav sample of your choice. I personally downloaded "atmos" (that is to say, the file atmos.wav) under the Popular category. Place this file somewhere convenient (I picked ~/.config/pipewire/ myself), and remember its absolute path.

3. Open the config file you downloaded in step 1 and find-and-replace all instances of hrir_hesuvi/hrir.wav with the ABSOLUTE path of the .wav file you downloaded. Save.

4. Change your sound output device (in system settings, etc.) to "Virtual Surround Sink".

It should work now. Should the volume seem low, you can try to switch to another sound output (in my case it was Analog Stereo Output), and switch back.
