Comment 30 for bug 969001

Ahh, sorry, I didn't understand your first problem description you posted in this bug report. I though the playback speed is alright, just the sampling rate used is incorrect.

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?
