Thank Tobias, that's really great news.
Just so I'm clear, let me verify my understanding of how you are talking
to the USBaudio.sys driver. I'm guessing that you are using the kernel
streaming interface, that is you are calling DeviceIOcontrol with
IOCTL_KS_READ_STREAM and/or IOCTL_KS_WRITE_STREAM?
Thanks again!
Andy
