Also, watch out for 20 and 24 bit little-endian USB devices - which
of course you don't have to anymore because we publish all devices
as floating point!
As for the recent discussions on this topic...
In 10.1 we'll have a new API - AudioConverter - that will do many
of the things that the SoundConverter of the SM does - including
this often-times talked about int->float, and this functionality
will be published also through the DefaultOutput unit. More details
on that to come later.
Whilst on that topic - we actually do int->float more efficiently
than the code quoted in both of the previous posts:)

I would say that the conversion it is doing is to 44.1 since that
is the only
rate the hardware will except. You could easily do the sample
conversion
yourself and send it to the sound manager
But watch out for the possibility of a 48kHz hardware sample rate
(some USB devices ...).
