Thanks to all involved for working on usb audio v2.
Last night I installed the 20100226 snapshot. I did a little testing with my XMOS board using toslink out into may DAC. I tried various files ranging 16bit/44110kHz-24bit/192000kHz. The 44110 files had quite a bit of static, the higher bitrate files were better. As you stated the sampling rate is not correct and be verified by looking at the flashing LEDs on the XMOS board. They should flash faster as sampling rate increase. In this case no change was observed.
Yes - this is all do be done. The sample rate setting is done with a different type of class request, which also addresses the interface now, unlike v1 devices which send that to the endpoint. But that's just one out of many differences that need to be addressed, and it's still a long way to go. I'm on it :)

I upgraded alsa to 1.0.23. The XMOS device is working great with the exception of some mild clicks here and there. Is this a known issue or might it be a problem with my specific configuration?
What specific configuration are you testing with? As you have such an evaluation kit, I believe you're also provided with the XMOS development platform - which firmware did you install to the board?
