Hello Andrew,

It sounds as if there are errors being produced by either the USB Audio
driver or somewhere on the stack below that. What error messages (if
any) are you receiving in your requests? There is nothing in the USB
Audio driver that prohibit higher sample rates of 96kHz unless perhaps
you are trying to receive 6 or 8 channels at 24bit or some other
combination which would max out USB bandwidth.

Sincerely,
DJ Sisolak

Hi Mitch,

I have varied the size of (each of) the five buffers in my ring between
5760 bytes and 23040 bytes without a noticeable change in behavior.

Sincerely,

Andrew
