Hm, sorry for what turns out to be a bit of noise. I just found some old threads online about bugs in the Intel USB chipset[1] which I would guess is in a large majority of consumer laptops, maybe even desktops, on the market today. Those bugs seem to be the cause of the "broken pipe" when ALSA tries to talk to the device.

I guess I'm lucky to get 2-in, 2-out.

Needless to say, I am exceedingly annoyed about this. One more stupid hardware thing to check when looking at new machines...
