Sound lag while choppy with waikiki driver ?

I'm use vistax86 and windows 2003 ,When i'm use any application like game,media player with build-in speaker-Altec Lansing while sound it's comming at choppy frequency [ex.hook ryhm or shot the gun] sound are lag and hdd led are alway light ?

but i'm nothing to get this trouble when use line-out like headphones ? [and hdd led are not alway light [i'm test it again with BF2142 and see intro movie it's real lag when choppy but while i'm insert the headphones title are smooth right now !] ]

Since I'm born I'm never get trouble like this and it's crazier
I'm got to chat with HP technical support and he recommend me to uninstall UAA Waikiki driver and Conexant HD driver and reinstall new with the follow link but it's not help anything

sound lag still haunting me....

I'm think it's cause from waikiki driver is develop for xp only and it's due to hardware malfunction when use with other os
yes,I'm reinstall 2003 to many times and use vista x86 it's still be this

HP should be know about this problem well but they's never release a new driver for the other operating ,specifically like Vista ! it's most important because it's about stable of system ,They will be allow the pavilion user who have waikiki hd audio chip still use old xp driver and problem still continue ?
c'mon try to working with conexant to closed more ?

it's not a good experience with my 1month 20days pavilion dv2107tx [dv2000 model] i'm just bought it with my working money

anyone have problem like me ? whichever it's only just me ?
sorry for my english but it's want to share my experience to anybody...

thanks...
