What happens when I try to record and unmute the microphone on Volume Control GUI or alsamixer is that I get a noise that gets louder if I put more volume on the microphone.
$ lspci | grep Audio
- Code: Select all
00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05)
01:00.1 Audio device: nVidia Corporation High Definition Audio Controller (rev a1)
$ lshal -m
This doesn't change anything when I plug or unplug microphone or phone.
