The last statement sounds like you're sharing a hub with another device that has reserved bandwidth. For example, a USB webcam will often do this. Audio will work for a while and then get pre-empted.
For A/V devices, USB bandwidth is reserved in advance; it is not possible to have other device interfere (as long as the controller driver is written correctly ...).
Thanks! Indeed, when deactivating bluetooth (in both kernel 3.2 and 3.5) the sound is back to normal
I'd guess that that particular USB port and the bluetooth controller share an interrupt.
is it actually fixable if we wrote better drivers?
Apparently, yes.
