for your next debian release
include the most common drivers for USB sound cards,
like: EMU202, C-Media Audio Adapter and others, like it is included

Your request is very reasonable for me.
I remember it was discussed here too.
I will forward your request for the next release.
@harry4516: you can also grab the kernel sources from Linaro’s GitHub repository and compile a kernel with support enabled for the devices you want.
