Hi,
I own an audigy card (Class 0401: 1102:0004 (rev 03),Subsystem: 1102:0051)
and the DTT3500 speakers. I tried to use the digital out of the card but
it works only with the creative oss/free drivers. But not with alsa.
In the docs from creative oss drivers I found that :
IOCFG Register (fn0 - 0x18)
--------------
The upper 8 bits are inputs, lower 8 are outputs.
Inputs
------
The following are used to detect if something is plugged into the
card (use 'dbgemu -d f' to see this register (0x18)):
0x2000 - center-sub/digital-out Jack
0x4000 - Front Jack
0x8000 - Rear Jack
0x0100 - Audigy Drive's Headphone Jack
Output
------
0x0040 - Disable front + rear + center/sub analog output
0x0004 - Enable digital out
So there was a possible mistake in the alsa driver. I made that patch but
it didn't work :(

Any idea to get this output working ?
P.S. : sorry for this long mail and my poor english
