Hi everyone,
Recently I’ve connected an external microphone to my laptop (via USB-C), that happens to have a headphones jack port, which I don’t plan to ever use. However, this has created all sorts of new problems for me.
PulseAudio detected that as two sinks (RODE NT-USB x2 + monitor speakers + laptop speakers on the screenshot below):
One of the first issues I’ve experienced was that on system start it would set the microphone output by default so I had to manually switch it back to my speakers. Finally inside pavucontrol I unchecked the “Set as fallback” option and that fixed it.
The issue I still have is that volume up/down buttons stopped working. They try to change the microphone audio sound even though it’s not active (the HDMI sink is “running”):
Because of all that weird behavior, I just want to remove this microphone sink from PulseAudio completely. I only want to use it as a source. I’ve searched on the internet but without any luck.
The result of `pactl list sinks`
Sink #63
