Ok guys as the new release of Frodo coming i wanted to know about its new audio engine and will ihelp my situation.

setup:
Receiver: Onkyo tx-sr603x (no HDMI I use the SPFIF connection from my motherboard)
Speakers: Infinity TSS-750
Motherboard:ASRock MB-A75M
CPU:AMD A8-3870K

My Problem is for the most part sound is ok, but seems to get rumbly (over modulated during backgound music in the movie it tends to get a little annoying.

I'm assuming you're passing DD/DTS over optical. In neither Eden nor Frodo is it in any way "modulated" when directly passing thru. If you are making XBMC decode the audio (for example for built-in volume control) there's a few things that could cause that, but would need more info.
