|  Re: Mixing raster interrupt with timer interrupt?
TED timers are driven by the system clock. They are 1/8th of the single clock, AFAIR.
It is hard to diagnose some code without seeing it, but either you are using the wrong timer (not the first at $FF00/01), using it wrong (if not the first, it must be set again and again) or TED DMA jitters your timing. Or even it gets mixed up with raster interrupt if you are using both.
Edit: Yet another idea. Are you playing full 4 bit samples or did you normalize it to the 0..8 domain?
