thanks, applied now to cvs.

Hm.. It seems then that after all that the Audiotrak Prodigy 7.1 is 
identical to Terratec Aureon, except that the later has optical digital 
IO instead of coaxial. The headphone function is also implemented in 
Audiotrak Prodigy 7.1 driver. I used to think that it was a difference 
between the Prodigy and Terratec Aureon. If everything else is the same 
(i.e. wiring inside the card) then we can  merge the two drivers into 
one since they are almost identical (prodigy.c and aureon.c).

I also have a dump from the communication of the windows driver with the 
AC97 codec of the card which is used for mixing the 4 internal 
connectors (the communication is through a XIlinx programmable device 
and so it was difficult to implement).  I believe that the dump can be 
used to add the support of the AC97 to both Prodigy and Aureon. I will 
do it sometime when I find time but if anyone is interested I can send 
the dump.

Cheers,
Apostolos

It would be really nice if support for the AC97 codec could be added. 
(I'm afraid I wouldn't be much of a help in this field as my current 
programming experience is rather low)

I agree - a merge of prodigy.c and aureon.c would be the right thing 
because as far as i know, the only difference (apart from the type of 
the digital io connection) is the content of the eeprom (and maybe the 
frequency of the crystal).

By the way, was anyone using an Aureon or Prodigy able to get a signal 
from one of the digital inputs? Currently the command 0x0200 from 
cs_inits[] sets the CS8415A's input multiplexer to RXP0 which is, at 
least on my Aureon, connected to the cd-spdif input. But unfortunately 
I'm neither able to record the signal applied to this input via the 
spdif device nor is it possible to monitor it by setting the "H/W 
Playback Route" control to "IEC 958 In". Any feedback/solutions/hints 
would be appreciated.

Christoph Haderer
