I've been working on this problem for some time & i'm clean out of ideas. Some time ago my sound started to decay i.e. every few seconds the music/voice would distort very briefly. I got over it during the following months by using several methods which seemed at the time to work but the fault always came back. I did windows restore, I rebuilt the Windows media player library (several times), i cleaned the registry, i updated my sound drivers, i have run microsoft repair centre fixes & i have searched countless forums but it keeps coming back. Sometimes the problem goes away for a day but returns later. this made me think its a heat problem but according to my heat probes, all is good.
My specs are; Windows XP (service pack 3 build 2600), M/B is ASUSTek M2N68-AM plus, CPU is AMD 2.7 gig Athlon 7750 dual core, Display is Nvidia geforce 7025 630a & my sound is Realtek High definition Audio (no seperate sound card).
This is my first post so i hope i have explained everything clearly & I look forward to hearing from you.
