I believe you that the kernel in wheezy is 3.2 but I bet to get the kind of
performance you want out of your XMOS usb interface will require something
newer!
If you want to test with aplay (and you SHOULD want to test with aplay) you
need to convert your flac to a wav file. You can use the flac command line
tools to do that.

Really, you need to stop trying to make a 3.2 kernel work and try something
around 3.11 or 3.12.
If you are reluctant to find a newer pre-built kernel and don't want to
build one yourself then I suggest you try Ubuntu 13.10 on a USB stick just
to see if 3.11 works with your device.
