Hi,
my soundcard is an onboard AC97 CK9804 NVidia. I use snd-intel8x0
module. Everything works fine except recording sound. When calling
arecord -f cd buffer.wav
the program infinitely hangs, and an strace shows that it is the poll()
call that does not return. After interrupting, a wave file of 44 bytes
which is the header only is left. My setup is Kernel 2.6.21.3, all
ALSA-software is updated to the latest version, that is 1.0.14(a).
In a previous setup with an older ALSA version and kernel 2.6.16.11
recording did work with the same hardware. Now that I updated all ALSA
software, even with that older kernel version the same recording problem
came up. From that I concluded that it is somehow related to the
ALSA-lib version. I have tried to downgrade ALSA-lib down to 1.0.0 to no
avail.
I have also made tests appropriate if this would be an interrupt problem
(using pci=noroute et al) which also did not solve the problem.
I have scrolled though the archives of alsa-user and there have been a
few posts regarding the same problem (but with other chip sets).
However, in those threads no definitive solution of the problem has been
discussed. So I try it again.
Your comments and help are much appreciated,
Thanks,
-Rainer
