After some failed attempts to get a dc-20 working, I want to give it a
try with a dc-30. :-)
I have a 2.6.14.2 kernel with alsa. The device is working with xawtv.
But when I try to record with lavrec it segfaults:
/usr/bin/lavrec -f a -i P -d 2 test.avi
**ERROR: [lavrec] Error initializing Audio: Audio task died. Reason:
Error mapping audio buffer - Input/output error
++ WARN: [lavrec] Not ready for capture (state = 0)!
Segmentation fault
When I add the -U option I get this error:
/usr/bin/lavrec -f a -i P -d 2 -U test.avi
++ WARN: [lavrec] Unable to set negative priority for audio thread.
++ WARN: [lavrec] Pthread Real-time scheduling for audio thread could
not be enabled.
**ERROR: [lavrec] Error reading audio: Audio task died. Reason: Error
Sound driver returned partial fragment!
- Input/output error
Segmentation fault
Here is some gdb information:
(gdb) run -f a -d 2 -U test.avi
Starting program: /usr/bin/lavrec -f a -d 2 -U test.avi
(no debugging symbols found)

I also tried to record sound with record, and this works fine.
Any idea?
