Well I got a product brief document from Via, it's confidential so I can't post it. But I can say that while it doesn't support asynchronous transfer, it does support 11 isochronous endpoints (5 in, 6 out) and a "feedback" endpoint which somehow guarantees lossless transfer.

This is all *very* promising. Even more so now that I see C-media is also keeping up with technology. Not a surprise, their current chip is very widely used, almost as much as the TI solutions... (from what little I can tell).

I'm most interested to hear what the driver requirements are. Will these work with standard windows/linux/mac drivers (OS X "core" audio?) Or do they require custom drivers similar to high speed firewire solutions?

Anything about driver support in the VIA docs?

Thanks!

Confidential? lol

Did they make you sign a NDA? If not, please post away.

C-Media has had that info up for over a year, but I have yet to see any information that proves it actually exists. As far as I'm concerned it's the Lock Ness monster.

very interesting indeed, the only thing stopping me from embracing USB tech in any of my DAC builds has been the lack of forward compatibility with HiRez content. this control mechanism sound good too; perhaps i'll shoot them an email
