Summary: NVIDIA CK8 ALC655 SPDIF passthrough
Description:
We're using a motherboard with nVidia nforce2IGP chipset, and the sound
device on this board is NVidia CK8, Realtek ALC655 rev 0. The motherboard
is MSI K7N2GM2, and SPDIF passthrough works fine on Windows XP with stock
realtek drivers.
On Linux, I'm using the latest ALSA CVS (29.04.2005.) on a 2.6.10-ac12
kernel.
I've been able to make a 2 channel pre-decoded SPDIF output work by using
the hw:0,2 device. If I use the default device, there is no sound on
SPDIF, regardless of the SPDIF related controls in mixer. The controls in
the mixer are:
However, I'm having trouble with AC3 passthrough, I'm using ac3dec -C from
alsa-tools CVS, and I get no sound.
I'm attaching the archive with the output of iecset and
/proc/asound/card0/codec97#0/* files during the ac3dec run, and when
idle.
Maybe the fact that decoded SPDIF output is not working until I pass it
through the hw:0,2 has something to do with this, how can I make ac3dec -C
use hw:0,2?
