I'd also like to add to this discussion that you can't really compare glitches in graphics/animation to glitches in audio. In general we (humans) are much more sensitive to glitches in audio than to frame drops in animation. You can usually get away with a 100 ms loss in an animation every now and then, but you can't as easily get away with a 1 ms glitch in your audio.

Most systems (DVD, DVB etc) prioritize audio over video. This can be seen when switching channels on some TV boxes for instance, where video stutters into sync with the continuous audio - it's hardly noticeable, but it would be horrible if it was the other way around (stuttering audio).

In other words, an audio API should provide continuous operation even under conditions when a graphics API fail to do so.
