Package: alsa-base
Version: 1.0.17.dfsg-4
Severity: important
The mic inputs, internal or external, cannot be "captured" (recorded)
by usermode apps including: arecord, skype.
Note: mic input, both internal and external, is controllable by
alsamixer. That is, mute, level and boost controls have the expected
effect as heard in both the onboard speakers or headphones. The
onboard speakers are muted when headphones ar plugged in (so that
sensing works). The internal mics can infact feedback thru the internal
speakers if boost
and level are set high enough.
So, input is being preamped and routed to output, but this "rouing" is
not accessible to apps.
I have verified this same behavior with kernel 2.6.30-bpo.
There are numerous reports of similar symptoms in a variety of other
netbooks\laptops that use the snd-hda-intel driver. Some Ubuntu users
report that some combination of updates with the 2.6.30 kernel have
resulted in a functioning audio subsystem on the HP 2140, but they all
required an update to pulseaudio, which my lenny\lxde system lacks
(and I'd prefer to avoid if possible).
I've chased a number "fixes" for this issue over several days. None
have resolved the issue for this netbook\os combo. I suspect "pin
assignments" around the "capture" devices in the AD1983A driver, but
not for any solid reason.
This is important for me as I intend to use this machine for audio\video
recording.
As an aside, audio is recorded (and real-time monitorable to the
speakers\headphones) by Kino when sourcing from /dev/raw1394.
