Summary: headphone output loops to microphone input
Description:
I cannot use the headphone port when using full duplex on my laptop. Here
are four scenarios, and the results:
1. System speakers, no microphone plugged in
RESULTS:
When recording from the microphone input, there is no sound. As expected.
2. System speakers, microphone plugged in
RESULTS:
Only the sound that should be picked up by the microphone is recorded
through the microphone input. As expected.
3. Headphones plugged in, microphone not plugged in.
RESULTS:
No sound when recording. As expected.
4. Headphones plugged in, microphone plugged in.
RESULTS:
Audio coming in through the microphone input is a combination of the
expected audio and the audio that is being played through the headphone
output. This is the problem.
Could this be an ALSA issue, or should I have the laptop hardware looked
at? I should note that this also happens if I use the OSS driver. That
doesn't mean it's not a driver issue, though; it could be that some
register is not being set up properly.
The loopbacked volume is lower than if I set Mix or Mix Mono to be the
capture channel. I'm using jaaa with noise output turned on to monitor.

Ah. Yes. Turns out to have been an issue with my microphone - it's just
hideously leaky, I suppose. If I use a different mic, there's no problem.
Sorry for not checking back after I determined this.
On the plus side, the bug can now be closed.
