You're right: "if".  ;)
But found some more info about the other chips:

Perhaps I misunderstood that test at "icrontic" - there was a comparison of

the chips, and this was suggesting, that there are four versions of the

card; probably wrong conclusion.
The testers are publishing a bit contradictory informations: f.e. on the

page:  http://techgage.com/article/chaintech_av-710_71_sound_card
First you'll find: "VIA ENVY 24PT", several verses down a remark: "The heart

of the card is the Envy24 HT-S Chipset" - with a photo on the side. A photo

of... ENVY 24PT. Immediately below - image of ENVY 24HT-S.   :-O
What a pity; the card has quite good reviews. OK, must look further...
