Logitech G930 Headset - Microphone not working

Hello,

I am stuck trying to troubleshoot this problem. My Logitech G930 Headset is detected by pulseaudio and audio playback is working correctly. However I can't get the microphone working. It's not muted in pavucontrol but arecord | aplay doesn't play anything. Wild googling didn't yield any solutions. I would appreciate any guidance for things that I should try.

Thanks!

thegromph,

Welcome to Gentoo.

A few things to look at. Headsets usually have a mute switch.
On some its a physical switch, on others its a signal to software.

Sound inputs usually need to be selected correctly in your mixer software.
Further, thate ore at least two classes of mic, those that need the 20db Mic boost and those that don't.

The last complication is that a headset is usually its own sound card. This means that you most likely have two or more sound cards, so you need to pick the input from the right sound card too.

Thanks NeddySeagoon,

The headset itself isn't muted (that would have been embarrassing). I also tried cranking up the gain in pavucontrol but it still doesn't seem to be working.

Here is the output of pactl list so you can see what other sound devices there are. Seems like the correct profile is in use for the card and all the other inputs are disabled.

Hello thegromph,

Just a shot in the dark... yours may be a case when a kernel-usb-sound module "quirks" option needs to be activated.

Hi ogenos,

Thanks for the idea. How do I activate that option?

Hey thegromph!

I have the G930 to and this headset work fine for me on gentoo. I dont know wich exactly kernel flag he means.

Perhaps the solution is easy: Wich soundsystem do you use? Do you use alsasound? Do you checked with alsamixer the levels of the channels, has the micro full power here?

I think it is a usb problem. I found out that the microphone works using the usb hub in my keyboard but there audio does not work. I realized that I had usb 3.0 so I enabled that in the kernel but then both audio and mic didn't work. So I think its a usb 3.0 problem but enabling that in the kernel doesn't help. At least I know its not a muting problem and that pulseaudio is set up correctly. Any more ideas?

Update: I enabled USB 3.0 and disabled USB 2.0 in my kernel. My headset now works in the USB hub (which I assume is USB 2.0). Any idea what else I might change or am I doomed to crash my mouse into the dongle sticking out from my keyboard.
