    Microphone jack not working

    Hi all,

    I can't get the mic on my Sennheiser headphones working with my front audio panel! The headphones have a 4-pole 3.5mm connector while my front audio panel has two 3.5 jacks, so I've got a 4-pole splitter that gives me a speaker and a microphone jack.
    - When I plug the two splitter jacks to the front panel, I can hear just fine but the microphone doesn't record anything
    - Same if I remove the splitter and plug the 4-pole headphone jack into the "headphone" jack on the front panel
    - If I remove the splitter and plug the 4-pole headphone jack into the "microphone" jack on the front panel, I can record sound but can't hear anything.

    And the kicker: the splitter works just fine in Windows, which I'm dual-booting to. It also works on the back audio panel (and I'd use that, but my cable is too short). Which makes me think that this is a software issue of some kind.

    I've fiddled around in pavucontrol to no avail. I did discover that pressing the volume or mute buttons on the remote results in a big reading on the input. Some kind of click noise, I guess. The motherboard is a Gigabyte AORUS Z390 and the case is a Fractal Design Define C, and I'm assuming I've wired everything up correctly since it works just fine in Windows. Hope someone can help!

    The plot thickens. I accidentally plugged the green "speaker" part of my headphone splitter into the pink "mic" jack on my front panel. That gives me the same result as just plugging the headphones in the mic jack: I hear no sound but the mic is suddenly picking up what I'm saying.

    Try plugging the headphones and mic in as you would on Win. Leaving them plugged in, reboot the machine and see if that works.
