I can confirm Pawel's observations. I have the same switching behaviour:
- In (gnome) alsamixer there is a distinction between internal/external/mixed
- In the audio settings applet (I assume this uses pulseaudio?) there is only a single mic channel.
- If alsamixer is used to switch the input to either "mixed" or "internal", the settings applet window immediately switches to "muted" on the single channel.
This occurs also when using alsamixer in a terminal, and it occurs also on a clean install without any (other) programs running.
