Music hang when another sound plays or volume change ?

[Sagilo]

Hi All

I'm using latest ver over DHD
When i hear Radio, every other sound played or even when i changes volume (!), stops the radio like and it sounds like i disconnect the headset. (like this noises of shutdown)
It's really annoying, i know a few versions before it was OK and i was able to change volume fluently without getting this weird hangs...

Any ideas? :\

Thanks !
