Summary:                    emu10k1: sound chopped when passthru enabled
Description: 
When I play a DVD with AC3 passthru enabled, the signal is correctly send
to my AC3 decoder but this signal is chopped. I've a little led on my
decoder to show if dolby digital is enabled or not and this led blinks
instead of remaining enabled. So the sound is also chopped and a DVD can't
be 
watched this way.

Well, the in-kernel ALSA version lags behind the current ALSA usually by a
month or two.  Can you verify that the problem still exists with ALSA CVS?
 If so, please close this bug and open a new one under alsa driver -> PCI
- emu10k1.

I would verify it, only if I could get it compiled. 
Both 1.0.7 and CVS compilation fail with following:

[...]
 CC [M]  /usr/src/alsa-cvs/alsa-driver/kbuild/../drivers/serialmidi.o
/usr/src/alsa-cvs/alsa-driver/drivers/serialmidi.c: In function
`tx_loop':

arg 3 of pointer to function makes integer from pointer without a cast
/usr/src/alsa-cvs/alsa-driver/drivers/serialmidi.c:327: error: too many

make[1]: *** [modules] Error 2
make[1]: Leaving directory `/usr/src/linux-2.6.10-rc2'
make: *** [compile] Error 2

I tried it with both gcc 3.2.3 (Debian), 3.3.5 (Debian 1:3.3.5-2) and
3.4.2 (Debian 3.4.2-3). Looks more like Linux version incompatibility?
Am I doing something wrong?
