12.0 RC2 with /boot and /boot/msdos on sdcard and everything else on USB
connected hard drive (causing interference with the bus?). Otherwise
everything directly off the RC2 image + packages and a bit of configuration.
On repeating my tests (probably last done a few months ago with the
current snapshot) the sound was much better than I remember (almost
recognisable!). Maybe having the non-debug kernel is helping. Hope this
isn't a red herring.
