snd-usb-audio problems with 2.6.18

A recent 2.6.18 kernel upgrade on one of my machines broke usb audio.

I'm using a TerraTec Aureon 5.1 USB MKII to feed ac3 audio to a
receiver, but after the upgrade, trying to play any audio (tried aplay,
mplayer, xine, etc...using both oss and alsa audio) results in the
kernel log being filled with the message:

"cannot submit datapipe for urb 5, error -28: not enough bandwidth"

Unfortunately the upgrade was from 2.6.14 (yes, it's old but the machine
has no network connection usually) so there is quite a lot of
differences to the snd-usb-audio driver in the meantime.

Unless someone has suggestions as to a simple fix, I guess I'll
start testing kernels in the 2.6.14 <-> 2.6.18 range soon to try to pin
down a certain changeset...
