Title:
headset microphone no longer detected and therefore won't record
Status in “pulseaudio” package in Ubuntu:
Confirmed
Status in “pulseaudio” source package in Quantal:
Confirmed
Bug description:
I'm not sure what package this should be targeted to, so feel free to
reassign.
I upgraded my main system to Quantal earlier in the week. I have a
headset with a microphone and headphones that I use with my laptop,
which has a headphone and microphone jack. On earlier releases when
attending a meeting, I would plug the headphones into the headphones
jack and the mic into the microphone jack and both would work without
issue. In 12.10, only the headphone works automatically.
Using gnome-control-center's sound settings, I observe on the output tab:
* plugging in the headphone causes 'Play sound through' to change to
'Headphones'
* unplugging the headphones cause 'Play sound through' to change to
'Speakers'
Using gnome-control-center's sound settings, I observe on the input tab
(notice there is no change-- it always says to use the Build-in Audio):
* plugging in the microphone causes 'Record sound through' to change to
'Microphone - Built-in Audio'
* unplugging the microphone causes 'Record sound through' to change to
'Microphone - Built-in Audio'
Looking in alsamixer, pressing 'F4: [Capture]' I see settings for 'Doc Mic'
and 'Internal Mic' (and Boosts for each). I observe:
* plugging in the microphone causes no change in 'Doc Mic'. It's levels are
'0' and it is not set to capture. I can't find a way to enable 'CAPTURE" in
alsamixer
* unplugging the microphone causes 'Internal Mic' to display 'CAPTURE' in
red, with levels at 100/78
Looking in pavucontrol, and clicking 'Input Devices', I can select a
'Port'. The 'Microphone' port is displayed by default. However I am
able to force levels with this. When the microphone is plugged in, the
'Microphone' port (internal mic) does not record. If I change the port
to be 'Dock Microphone', I can record. Furthermore, after making this
change in pavucontrol, I observe in alsamixer that the 'Doc Mic' is
now setup for 'CAPTURE' with levels at 96/96. If I unplug the
microphone and plug it back in, I must manually pick the port in
pavucontrol to have the mic work again.
What appears to be happening is that everything works fine for the
internal speakers and mic. Everything works fine when I plug in the
headphones. When I unplug the microphone, the headset mic ('Doc Mic')
is automatically set to not capture and the internal mic is. When I
plug the headset, the internal mic is set to not capture, but the 'Doc
Mic' is not set to capture. pavucontrol allows me to force using the
'Doc Mic'.
WORKAROUND: after plugging in the headset microphone, launch
pavucontrol, go to 'Input Devices' and select the 'Dock Microphone'
port.
