Microphone 1 not working on Sound Blaster Rx

Hi there,

I could really use some help again—audio on Linux has always been a bit of a challenge for me.

I recently got the “Creative Sound Blaster Audigy Rx” sound card, and while it generally performs well, I just can’t get the microphone to work. I mainly need it for Discord, but it would be amazing if I could get it fully functional.

Usually, I don’t struggle much with setting up my system, but this time it’s been pretty frustrating. Either the sound card isn’t cooperating properly, or I’m overlooking something really obvious.

I’ve tried a lot of settings in Alsamixer and PulseAudio Volume Control, but nothing seems to do the trick.

Yesterday, I came across this link:

Is there a chance that PipeWire has some preconfigured settings affecting this? Could I try uninstalling it to see if that makes a difference? Honestly, I’m not entirely sure what it’s doing on my system anyway.

Thanks a ton for any advice you can offer!

My Settings in alsamixer look like this:


But there are additional settings in PAV:

Im not sure what pipewire could have done here.

But maybe my settings are just wrong -.-
