Summary:                    ac3 passthrough not working on recent versions
Description: 
Using the following AC3 passthrough with mplayer works:
Linux 2.4.31
alsa-driver 1.0.8-7 (debian stable packaged)

Using Linux 2.6.15 (both with alsa-driver 1.10rc3 that ships with the
kernel and
alsa-driver 1.0.11) it doesn't work. The reciever just says "unlock" and
stays quiet.

The only change is booting with different kernels, no other config or
hardware is touched, so this must be a driver regression.

The card is YMF-754 based, connected with coax spdif to my HK reciever.

If you need more info, just tell me and I'll dig it up.

You may need to revert some patch related to SPDIF to find out the cause

I tried using a debian 2.6.8 kernel, and then AC3 passthrough works.
/proc/asound/version says ALSA 1.0.4 ...

Using a 2.6.14 kernel did not work (ALSA 1.0.10rc1).

So, any possibility of getting a list of what patches has been added to
ymfpci between v 1.0.4 (that works) and v 1.0.10rc1? It would help
narrowing down the candidates quite a bit...
