Headset microphone not detected

[seeji]

Hi,

I noticed that USB microphone (Logitech G733) is missing from audio devices. Sound cards mic and webcams mic are detected. USB headset output works as normal. I’ve used this same headset previously on EOS and also on my other PC’s with other distros without problem before this. I’m using either the same kernel or TKG on other PCs.

This EOS installation is ~couple of weeks old. Did full reinstall to get a fresh start. On previous installation Mic has also worked. I havent used mic on this installation yet so no idea if it was missing from the start or if its more recent problem.

I can see this mic in

alsamixer --view=capture

But under KDE’s system settings and audio control, it’s missing. Also applications like zoom and discord do not see this mic.

Im bit perplexed where to start troubleshooting. Tried replugging receiver to other USB ports, updating system, trying EOS kernel and ofc rebooting.

I kinda fixed this by adding microphone manually to pipewire conf via these steps:
arecord -l

**** List of CAPTURE Hardware Devices ****
---
card 3: Headset [G733 Gaming Headset], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

/etc/pipewire/pipewire.conf.d/microphone.conf

context.objects = [
    { factory = adapter
        args = {
            factory.name           = api.alsa.pcm.source
            node.name              = "microphone"
            node.description       = "Undetected Microphone"
            media.class            = "Audio/Source"
            api.alsa.path          = "hw:3,0"
        }
    }
]

systemctl --user restart pipewire

Any ideas why pipewire does not detect microphone automatically? I do not have any custom pipewire configs (before this one), and mic was working fine on previous installs of EOS.

Marking this as solved.
Manually adding a mic is more like a workaround instead of a real solution. Never found out what was the root cause, EOS live CD for example did automatically detect the microphone, but the installation did not. I decided to go for another full reinstall due to that.
