Perhaps I spoke to soon with my setup running fine. . . here's what's happening. I have my onboard SoundMAX plugged into my DD-5.1 via a coaxial cable, and a Playstation 2 plugged into the DD-5.1 via a TOSlink cable. The PS2 outputs sound fine, and I get no crackling or stuttering. The coax source though, my computer, will randomly, anywhere from 10 minutes to 45 minutes begin to stutter - the sound will 'miss'. It happens to all audio passed through the coax (games, winamp, mpegs, etc.) The effect seems to get worse with time. Switching the DD-5.1 off and then on again clears up the problem for about another minute, then it returns. The DD-5.1 itself seems to function fine otherwise(again, the PS2 TOSlink connection has no problems), and doesn't get overly hot. The coax cable is a new Monster IDL100 cable, 1 meter long. I've refit the cable a few times.
