[SOLVED] Mic not working in Teams/Discord

Hi, so I have my Mic connected to a Scarlett 4i4 and the Multichannel Input selected in the Voice & Video Settings.
However, while the audio output works without problems, Discord does not recognize any input from my microphone.
I'm using this mic all the time with Google Meets and Teams on the same machine and haven't had any problems there.

Re: [SOLVED] Mic not working in Teams/Discord

So out of a sudden it doesn't even work in Teams anymore. I don't really know what I have to do to even start fixing this

Re: [SOLVED] Mic not working in Teams/Discord

Did you disable remixing/use-all-channels in pulse configuration? More generally speaking you want to find out which actual channel of the "multi-input" your microphone actually corresponds to (... did you make sure it's plugged into the same "correct" input every time?) FWIW what output do you get from 

amixer -c2

If you've identified the correct channel you'll want to make a remap-sink config that maps a mono mic input to the corresponding input channel on the focusrite so that applications don't throw a fit if they suddenly see a multi-channel input they can't handle.

Re: [SOLVED] Mic not working in Teams/Discord

When I run 

amixer -c2

I get no output at all.

In Audacity the Focusrite is shown with 6 Input-Channels my mic is on channel 1 confirmed.
I tried figuring out how to create such a remap sink and used this command

pacmd load-module module-remap-sink sink_name="Mono-Focusrite-Mic" master=alsa_input.usb-Focusrite_Scarlett_4i4_USB_D885Y2308129CF-00.multichannel-input channels=2 channel_map=mono,mono master_channel_map=front-left,front-right

But that didn't do anything. Can you probably help me figuring out what the correct command might be?

Re: [SOLVED] Mic not working in Teams/Discord

You'd want a mono channel and a source rather than a sink (sorry I notice I mentioned sink rather than source), so rather 

pacmd load-module module-remap-source source_name="Mono-Focusrite-Mic" master=alsa_input.usb-Focusrite_Scarlett_4i4_USB_D885Y2308129CF-00.multichannel-input channels=1 channel_map=mono master_channel_map=front-left

or whichever master_channel is correct. Then you can try recording with e.g. 

parecord -d"Mono-Focusrite-Mic" test.wav

if that worked you can move the applications to record from the remap source
