Hi,
I have an odd problem with audio recording.
When I plug my guitar to the line in/mic in, it plays. I can hear the
sound fine. So the input device seems to work correctly.
But when I try to *record*, no matter the application (audacity, rezound,
arecord) the application freezes and no output file is made. arecord
actually spits out a 44-byte header, and nothing else.
strace-ing the application clearly shows that the app just freezes.
Relevant things I changed after last time it worked correctly may be:
- the kernel (from 2.6.16 to 2.6.18-r6)
- alsa-lib (from 1.0.11 to 1.0.14)
alsa drivers are compiled in the kernel. I run x86, stable, gcc 4.1.1.
The audio card is: (lspci output): Multimedia audio controller: Silicon
Integrated Systems [SiS] AC'97 Sound Controller (rev a0)
I tried messing with alsamixer settings but with no avail. Relevant
kernel settings seem OK...:

Update:
- When I tell audacity to use ALSA directly instead of OSS emulation, it
doesn't hang anymore. But the cursor doesn't start.
- When I also tell audacity to use software playthrough, it seems to
start recording. But it records only silence.
In every case, arecord still hangs at the header of 44 bytes.
Any hint?
