Frank,
Thank you for asking! As Danijel
mentioned USB Audio 2.0 support is important for higher sample
rate / higher bit-depth / higher channel count hardware. If the hardware
does 24-bit 192kHz then USB Audio 1.0 cannot even do 2 channels. Even with
the more widely used 24-bit 96kHz, then channel count is limited to
stereo. If someone wants to just use 24-bit 96kHz for 5.1 playback, this
simply isn't possible with USB Audio 1.0.
Now that there are more USB Audio 2.0 solutions coming to
market, each company is having to develop it's own driver... and of course
each
will have varying degrees of success. Audio driver development is
generally not the core competence for a chip-set company so they end up
having a
3rd party company develop the driver. OEMs end up with the "not our fault"
situation where the chip-set company blames the driver company and the
driver
company isn't being paid to fix bugs. The end result is products that
don't work very well on Windows but work better on OS X.
As it is now, all of the USB Audio 2.0 solutions are having
to be qualified on OS X 10.6 (which does support USB Audio
2.0).
I think the key issue is market acceptance.
Microsoft never supported audio on FireWire in the OS, and I would say
there are
fewer FireWire audio devices on the market as a result. If Microsoft
supports
USB Audio 2.0 in Windows 7 SP1, I think you will see many USB Audio 2.0
devices
hit the market.
Thank you,

USB Audio 2.0 in Windows?
There are occasional questions
on this list about USB Audio 2.0 support in Windows. We (the Windows
sound
team) are curious to hear specific reasons- scenarios, business,
features,
etc.- that would be enabled if USB Audio 2.0 support was included in
Windows.
Are any of you willing to
share this? The more specific you can be, the better. If you do not want
to
share with the entire list then feel free to send a message to me
directly.
