I own the 'Asus P5WD2 Premium Intel 955X (LGA775) PCI-Express Motherboard'. I use the motherboard's on-board sound (Realtek HD Audio) and connect to a Sony A/V receiver using an optical cable. When I play sound with the 'Dolby Digital Live' button on, it sounds great, but every few seconds, the sound skips. (My A/V receiver then re-scrolls the 'Dolby Digital 3/2.1' message.) It's very annoying when playing MP3's which I often do. If I turn the Dolby Digital Live feature off, the sound does not skip at all but the quality is just not quite as lively. I am making do with this for now. Just wondered if anyone has come across this problem before? I have updated the Realtek drivers. Changed sound modes in BIOS between AC97 and HD Audio, etc. I simply want to be able to have Dolby Digital Live turned on without any skipping!
