Thank you for your answer.
I have seen the TS-7300 but we can't use it for some reasons :
- The mechanical size is too big
- The price is too high, because a lot of fonctionnality of this card
will not be used.
And in some case we won't need the second ethernet link.
For these reasons I think that the TS-7400 is a good choice, because
the daugher card will not be very complicated, and will be low cost.
I have different codecs and I think I will use one of these :
- WM8510 (Wolfson)
- AD1881A + SSM2250 (Analog Device)
-TLV320AIC26 (TI) (not AC97 but SPI)
