Title:
Pulseaudio refuses to use internal microphone input (Lenovo X300)
Status in pulseaudio package in Ubuntu:
Expired
Bug description:
Binary package hint: pulseaudio
Pulseaudio seems to have decided that the ALSA "Mic" capture device on
my machine is the only one it will use. "Internal Mic" is the correct
one (at least when no external mic is plugged in).
If I use alsamixer to switch to the correct capture device, the
pulseaudio volume controls instantly marks its input device as "muted"
(and no sound is captured with, e.g., gnome sound recorder). Un-muting
within the pulseaudio volume control again switches the alsa mixer
back to the incorrect "Mic" device (which captures only noise). There
doesn't seem to be any way to tell pulseaudio which capture channel to
use. Pulseaudio level meter show the same thing - noise when the
incorrect "Mic" device is active, but completely muted if alsamixer is
used to change to the right device.
Everything works fine if I boot a jaunty live disk - the alsa
configuration and device detection seems exactly the same, but
alsamixer can be used to switch active devices underneath pulseaudio.
Sound recorder and pulseaudio level meters show noise on the "Mic"
device, but correct capture when the "Internal Mic" is active. (And
muting with the pulseaudio only deselects the "Capture" level control
in alsamixer, it does not activate "Mic" and deactivate "Internal
Mic".)
This may be a duplicate of Bug #414215, but it didn't seem quite the
same to me.
