I can only vouch for one program, but this is reproducible. Running SimCity4 occasionally when an interrupt occurs, sometimes as little as an extra mouse click and always on a context switch, the sound from the program is lost and does not recover. The log for this is over 1400 lines, so I stuck it on my web site. Here is the URL.
