quite a lot of changes to the usb audio part of the library. However,
I'm not sure how to compile and test this version as a .deb package.
I'm also not sure this is due to libasound2, but the sarge -> etch
update did not change the kernel and all media players that I've tried
seem to have the same problem, so I suspect that the alsa libs are the
