Terratec DMX XFire DSP

Terratec DMX XFire DSP

[Friedrich.Ewaldt]

Hi Benny,
regarding your cs46xx DSP and codec list:
AFAIK the Xfire card has got a CS4624 DSP, not a CS4630. The main (only?)
difference should be the processing power (CS4624: 255MIPS, CS4630: 420MIPS).
I think the CS4630 can handle AC3 input through S/P-DIF whereas the CS4624
does not (because of the proc. power?). AC3 out should be working with both
DSPs.
Are there any more differences you know of?
Is there any possibility for me to check the codec type of the Xfire card
e.g. under windows or by looking at the components on the cards?
regards

Are you sure ?
If the Windows system properties tells say that's a CS4624 it can be 
becourse
it uses the same driver for both cs4630 and cs4624, as they are binary 
compatible.
If you do a "lspci" on Linux it will probably say that it's cs4624/ 
..SoundFusion (something), but does
not mean that the device really has a cs4624.

Just sounds strange for me that Terratec have choosen the cs4624 ....

Look at your card physically, you may find the codec chips close to the 
DSP chip.
It would be great if you could do so.

Hi Benny,

I'm quite sure. Have a look at the following link <;-)

(It was probably cheaper. The XFire was a competitive product to the
Soundblaster1024. It was about 100DM ~ 50EU ~ 50$)
