I may be wrong, but I guess in your case much of the problem lies in the fact that it's a usb soud-card. Just don't do an apt-get while listening to music. Yes, that's obviously not a solution, but why would you pretend to have perfect audio with an USB soundcard while doing heavy IO? For example, if you've got to burn a dvd with an external usb dvd+rw, is it a good idea to start doing heavy IO while burning the dvd? I guess not. Why is this any different?

If on your car, your windscreen wipers didn't work whilst your headlights
were on, is the solution to only use one or the other?

which is more important, getting the data on/off the disk fast (because you are working on something and the audio is just background music) or the audio (because you are playing a live concert and the disk I/O is just background logging)
as another poster mentioned, the definition of 'acceptable' is very poor.
larger buffers can solve most skipping problems (at the cost of added latency)
for audio-only playback, latency of a half second to a second could be acceptable (as long as you can silence the playback immediatly)
for video/audio playback significant latency is also acceptable, as long as you can know how much it is so that the video and audio can be delayed the same amount.
for recording, latency also isn't important
for live manipulation of sound (record sound, modify it, and play it back) latency is critical.

An uncle of mine once had a car whose wipers were powered from the engine's manifold vacuum -- they worked just fine when the car was idling, and would race across the screen when engine-braking downhill, but when powering up the other side in low gear they would just stop. Going uphill in a heavy downpour the driver actually had to lean out the window to see.
