Hello list,
The headphone and mic 3.5mm jacks on my Thinkpad X41 Tablet are
quirky. I want to throw it all out there for reference to others, and
in case the quirks are actually bugs. I'm using a cheap analog
headset.
(I can record & play audio fine with the right mixerctl settings.
There isn't a "problem" here except odd behavior for some of the
knobs.)
I have to toggle the bluetooth softswitch (Fn+F5 on my laptop) the
first time in order to use the headphone jack. Otherwise it just
outputs to speakers no matter the mixerctl settings or plug state.
Subsequent plug changes are detected ok.
The outputs.hp and outputs.hp.mute mixerctl settings have no effect on
the sound volume out the headset jack. (Are they supposed to?)
The inputs.mic and inputs.mic.mute mixerctl settings have no
discernible effect on the sound volume/quality of a recorded sample
(Are they supposed to?). A recording at inputs.mic=0/muted sounds the
same as one at inputs.mic=255/unmuted. The two settings do however
affect the level of buzz/feedback I hear through the headphones from
the mic when they are plugged in (in the expected way--larger volume =
louder buzz; mute on silences the buzz).
The inputs.mic.preamp both increases the volume of the recorded audio
(significantly) and increases mic buzz, as expected.
The record.volume has an effect on recorded volume, but it is the
opposite of intuition (record.volume=0 causes the loudest recording;
record.volume=255 causes a recording so quiet it can barely be heard).
The record.volume.mute does mute/unmute the mic as expected.
Cheers,
Anders.
