This problem also exists on the M-Audio Delta 410 which uses the same driver and is quite similar (from the computer's perspective) to the Audiophile 2496 I believe.
There isn't a control named "Master" or "PCM" on the Delta 410. The relevant channels are "DAC" and "DAC 1" through "DAC 7" for a total of 8. In order to get stereo volume control, I have to tell Ubuntu to control "DAC" and "DAC 1" together, as they are the left and right audio outputs.
I think that this non-standard naming convention is a part of the trouble in the log below
Here are the errors generated, starting just before things begin to go wrong:
