All in order. The biggest problem is that SBs don't maintain a constant clock and it confuses the DMA code, resulting in 'clicks' in the output. I had an AWE32 (the original) that absolutely hated streaming audio like vat. The Crystal chip in my PPro200 works like a dream, and I recommend cards based on them highly (like the A/Open AW35). Basically the SB wasn't engineered for a multitasking environment.
