I've only shown nodes that have the string "front mic" in them: Selected output of cat /proc/asound/card1/codec#0 is below.Not sure if this is normal or a problem, but the audio device listed in lspci is AMD, not Realtek:Ġa:00.1 Audio device: NVIDIA Corporation Device 228b (rev a1)Ġc:00.4 Audio device: Advanced Micro Devices, Inc.alsamixer and pavucontrol and the "sound" tab in settings look fine - it's unmuted, and the levels look fine:Īlso, the microphone is clearly detected in the sound settings "input" tab - the entry disappears when i unplug the headset, and reappears when I plug it in:.I suspect something might be trying to use the mic as a line out. The mic signal seems to track the output volume (i.e.I've checked the headset mic is working and I'm not just using the inbuilt laptop mic. The headset (phones and mic) are definitely working - tested on my laptop (Dell Latitude 5480, also running Ubuntu 18.04).I do also have an nVidia RTX 3070 that I think also has its own audio codec.Motherboard: Gigabyte B550 AORUS Pro AX (for Ryzen processors), which has a Realtek ALC1220.The headset plugged into front audio port of a Lian Li Lancool 215, which according to the manual is a TRRS port.
Shure SE215 with "RMCE-Universal Remote and Mic Compatible Universal Cable ", which has a built in mic.The headphones work fine, but the mic doesn't work - in sound settings and in pavucontrol, I'm getting no signal when I speak.
I have a headset whose mic input isn't working on my desktop running Ubuntu 18.04.
