The problem most probably lays in audio clocks. Values used by radeon seem to be: EVERGREEN_AUDIO_PLL1_MUL 00075300 EVERGREEN_AUDIO_PLL1_DIV 00177fa0 EVERGREEN_AUDIO_PLL1_UNK 00000071
Do you have fglrx installed? Is this possible for you to switch to the fglrx for a moment and do similar dump (using avivotool) while playing audio with it? To make debugging quicker: can you also dump "avivotool regsrange 0x500 0x600" just in case fglrx uses some other registers?
