I've done a quick test with the CVS code now, and it seems to work just 
fine, i just got some newbie
questions,  how do activate CONFIG_SND_CS46XX without modifying the 
Makefile?, how do
I activate the snd_printd ? , (without modifying config.h)

About the secondary codec on the terratex xfire card, can we try to 
trace exactly where it failed
to detect it, I would like to know.

On the "Turtle Beach Santa Cruz" now i know that GPIO7/GPIO8 on sec. 
codec controls back speakers, that's not done yet,
But I would like to know if current code at least detects the secondary 
CODEC successfully. In theory it should.

I would like to build a list with card and of DSP and codec (only cs46xx 
cards), please helpme to complete this list.

Hercules Game Theater XP
dsp: cs4630
primary codec: cs4294
secondary codec: cs4294
EPGIO2 controls ext. amplifier

Turtle Beach Santa Cruz
dsp: cs4630
primary codec: cs4294
secondary codec: cs4297A
GPIO7/GPIO8 on secondary codec controls back speakers support

Terratec XFIRE:
dsp: cs4630
primary codec:  ????
secondary codec:  ????
????

....


A small fix to cs46xx_lib.c, it does not make any sense calling 
playback_transfer before the PCMreader is linked or Playback controll 
register set to 0. && I would like to update the TODO text to something 
else.
