Can confirm with my USB sound card (a "Zero DAC Head Amp" - http://www.ebay.co.uk/itm/09-NEW-VERSION-ZERO-24-192KHZ-DAC-HEAD-AMP- USB- OPA2604-/110606578667?pt=LH_DefaultDomain_0&hash=item19c0aa73eb#ht_8674wt_1165). It isn't anything fancy in the USB department - just a USB -> SPDIF chip (lsusb says: Bus 001 Device 010: ID 08bb:2704 Texas Instruments Japan). I think it happened with my old USB sound card as well (Lexicon Alpha). Can check if you like.
Just upgraded to 12.04 and have the same problem. I don't think bug #569526 is the same problem since I only have one instance of Pulse running: ps aux | grep pulse 1000 2139 1.6 0.0 631444 7788 ?
