I wasn't thinking of while playing, that's too problematic. But since you mentioned, if we have a linked list of queued buffers, such a clip could be inserted to the front. Trouble if parameters (sample rate, etc.) are different. > The > problematic with this is latency due to buffering.

I was more thinking about loading a UI sample set into the buffer when the unit is idle, to be kicked out again on playback. But the main thing to me is the ability to pump the playback at all, for different file readers or game sound effects.
