Realtek HD 5.1 sound skips

[rabaneros]

hi

i have a GB 790 fxt with this sound card, and have a good sound, i have plugged a HT with an optical cable, but when i put the audio manager in 5.1 digital dolby (only in digital output), the sound (mp3, blu ray, dvd, games)skips randomly like 0.5 sec, every 3-4 secs, which makes an awful expierence

i have the latest drivers (2.40) and my OS is xp

but when i put 6ch or stereo everything is fine, but the quality is so much inferior compared with digital, without mention that i can not notice almost any surround effect

please help

btw sorry for my spelling, english is my second

thanx

I'm thinking it's an issue with your other specs. What other components do you have in your computer?
