Dropouts on music wav's

Hi,

I installed Frodo rpm on Fedora 18 box, XBMC worked OK with these files on compiled "Eden".

I have switched to the M/B H/W from pulse - no improvement.

Googled & found some info about AE being at fault, is that correct and if so has anyone any idea as to when it will work as they are not playable for me atm!?

Are there any settings I could adjust for me to play audio files atm?

Thanks for your time
