Summary:                    Scratchy sound through AC3 passthrough with
userspace version 1.0.9rc2
Description: 
I have an Audigy 2 ZS sound card connected via S/PDIF to a Logitech Z-680
decoder/speaker system. After upgrading ALSA userspace (alsa-headers,
alsa-lib) to 1.0.9rc2, with no configuration changes, all I got when
trying to play DVD:s using AC3 passthrough was scratchy noises, and the
external decoder indicated that it did not think it was getting AC3 data.
Software decoding worked, but not hardware passthrough. Both Xine and
MPlayer had this problem. I am not running aRts, or any other sound
server, and have no ~/.asoundrc file.

Downgrading to userspace version 1.0.8 made it work again.

I have no idea how to debug ALSA problems, so please let me know how to
generate any extra information you might require.

By the way, the "Product Version" field in Mantis doesn't let me select
any version higher than 1.0.8.

This issue still exists in version 1.0.9 final.

I've uploaded the results of `iecset` and `cat
/proc/asound/Audigy2/codec97#0/ac97#0-0+regs`, which are identical for
versions 1.0.7 and 1.0.9, and for playing PCM or AC3 passthrough.
