[PATCH] EMU10K1.conf

Hi,

I finally got my emu10k1 soundcard working with full 5.1 surround :-)

It took me 2 days, getting alsa to know and sound working properly. I
finally found out that /usr/share/alsa/cards/EMU10K1.conf was b0rked and
modified it so everything now works properly. Things which prevented it
from working properly were:

 - Rear/Center&&LFE Volume Controls in the config file were set to 0 and
locked!..

 - surround51 was statically bound to the non-digital output and locked
(to the analogue output), so there was no way to get surround sound on
my digital-out.

 - other volume controls were locked too, I had a look at Audigy.conf
and reduced the locked controls to the minimum required.


The patch attached for /usr/share/alsa/cards/EMU10K1.conf is actually
very trivial and a cleanup of the old file, it would be cool if you'd
apply the patch to the ALSA config file in CVS, I'm sure it would help a
lot of people which have no rear sound with the emu10k1.


/me now leans back and enjoys alsa and Lord Of The Rings II Extended
Version in _FULL_ Digital Dolby 5.1 :))))

best wishes,
dominik.
