Audio glitches in windows 7

Gday, I have a hp notebook i have recently reinstalled fresh windows 7 over windows vista not as an upgrade but as a complete new install the sound in windows 7 is amazing it sounds like you have a band playing in the room, I use this laptop mainly for my dj and use itunes to install or my songs, but i have noticed while playing these tracks occasionly there seems to be an audio glitch that comes through each song i play, only for 1 sec every 1 or two minutes very frustrating on such amazing sound, any ideas on how to fix or remove such a glitch problem, I was using ffdshow codecs but i unistalled them and that seems to have slowed the glitches down a bit, i am also using sandbox hd audio which when blended with 7's hd audio sounds amazing, your advice will be greatly appreciated regards Bender.

first suggestion I have to find out which sound card is in the laptop and then check with the manufacturer (HP) to see if they have an updated or beta driver available through their website. This solved it with my Compaq Cq60-211DX laptop with the W7 beta 6000 release... but after a fresh install of 7100 it was fixed so no need to do it again with the latest release for me.

Thanks i will give it a go, they dont have the windows 7 update on the hp website yet for my presario C700 so I will try the vista version I didnt install the audio driver as windows 7 already had it installed when i checked the audio and it sounds great except for the problem I mention regards Deke.

No good, still Glitching very annoying, it didnt do this on vista, but its bad on windows 7, this version is the 7100 version also, so what could be causing this to play up, it is a conexant audio hd audio card, presario c700 notebook, all the songs are what i used previously on itunes when using the vista operating system, now i have tried using the new media player as well as itunes on this windows 7 and the audio glitching is very Annoying any more suggestions please.

SRS audio SandBox was the culprit, I installed this for extra hd codec and equalizer which sounds great, but was causing audio glitches, now I have uninstalled it everything is great again, No more Glitches, so what would be a good equalizer to use for windows 7, the media 12 version is to small to see, there must be something that will work without interfering with the other audio codecs regards Bender.:)

12 has an eq in it.
