Okay, I tried the CS8420. Same deal. Intense noise in the right channel, and noise at higher digital levels in the left channel. No idea why it is doing this. The circuit works fine in the Empeg. I tried the clock out of the RioReceiver and an independent clock. Same result either way. It's gotta be something with the timing of the I2S, but what and why? I don't have a suitable scope to anaylze the timing, so I'm S.O.L. there. Anyone want to step in and finish this? Maybe we can work something out.
