use a h/w mixer control application (e.g. the
ugly and terminal-based
but-so-far-unmatched alsamixer) to set the capture source of the device
back
to, perhaps, "line in". then later,
switch it to the "mic".
Thanks, that worked. Strange thing is I actually had to set the capture
source first to "Stereo Mixer" and then to "Mic" - the other sources
(CD, Line, Front Mic, Stereo Mixer, or setting "Front Mic" and then
"Mic") all exhibited the same behaviour, but setting it to "Stereo
Mixer" and then to "Mic" and leaving it there allowed starting jack with
nothing connected to any jack. I wonder why the source selected *before*
switching to "Mic" matters!
Also, it seems there's no need to connect an
actual mic - connecting just
a 1/4" to 3.5mm adapter works just as well. I think I'll just leave it
plugged in.
correct. Jack sensing is a purely mechanical thing. there's no complex
"detection" going on.
