Bob,
I develop high end usb audio dacs. I might suggest the Creative Sound
Blaster X-FI 5.1.
I actually have not heard or used this one but I do have their X-Mod
device. It does enumerate for 5.1 and uses a DSP to actually create a
5.1 experience with only a stereo output. Being that it does enumerate
for 5.1 Audio Midi does recognize it as such. Therefore I would think
the X-FI 5.1 would also do the same and it's only $60.
All USB Audio devices can run up too 210k sampling rate. Most of the
problem comes into play as too if the devices is Full Speed (12MHZ) or
High Speed (480MHZ). You can have complaint devices at each speed.
For 44.1 six channel that is merely 576 bytes per millisecond or like
4.608Mbps which would work with controllers in either the 1.1
specification or the 2.0 in Full or High Speed.
I am not sure what you application is and I always say you get what you
pay for. But some of the bigger companies can crank out this stuff
pretty well. I mean I could never get to a price like that and have the
COG's of that device has.
As far as the MAC driving this... well it's going to do a hell of lot
better than a pc would. My custom controller runs USB in Asynchronous
mode at 24/96 which would be a little more than what you are asking at
16/44.1 * 6 and I have no problem even with older iBooks. The only
reason this would not work with a mac is if you have really old
machines. But most MAC's that have 2.0 USB Host controllers will work
fine and if you are talking about ones that can house PCI cards then you
should not have a problem.
Thanks
Gordon
