Sound card issue

Hi, i recently installed windows 7 ultimate 32bit on my laptop
and i love it to bits, but theres just one fallback thats making me want to change back to XP, and that is the sound problem, what the problem is that, when im playing counter Strike 1.6 online, and a grenade goes of, or lots of gun fire, the game jerks and twitches, and low FPS drop and ping spikes and allsorts of rubish

this is what iv done so far

1st.. laptop spec

model: toshiba equium m40x-148
CPU: intel pentium M processor 1.60GHz
RAM: 1.5gig 333
Hard Disk: 80 gig HD 4500RPM
GPU: ATI M Radeon x300 64mb PCIE
Sound drivers: Realtek AC97
(runs windows 7 like XP did, so no problem with performence of windows 7)

the first thing i did was disable that MMCSS thing in regedit.. then i read up some more on here, and found its best to leave that enabled and stop the other thing that helps online gaming.. that worked worked fine.. that stopped the high lag i was having.. but now im getting this annoying sound problem.. if i disable my sound card in device maneger.. the game runs smoooooth as a babys bottom, if i enable it.. i get this glichy/fps drop/lag/spikes and so on, i uninstalled it, reinstalled it, worked fine for 5 mins, then stated again, does anyone have any solution to this, becos if i cant get this fixed, then ill be going back to XP... im a big gamer when it comes to CS and i need it to run smooth, and atm, its just a nightmare when trying to aim...

thank you :)

Make sure all your drivers are up to date.

they are crispy, i made sure they was hen i reinstalled them :), but it still does it

Iv decided to go back to windows XP, at least i know everything i install or run will work.

what is this problem!!!! I have the same one EXACTLY...... and there is no solution.. my cpu is just sitting on the floor unplugged cause I can't play my favorite game D:

I can use onboard sound or my pci sound card and it still happens.

Any IRQ conflicts in msinfo32.exe?

i went back to XP and i used my onboard sound with the hd4650.. it performs great.. i just wish i could use my sound card with the graphics card as well as I want to have 5.1 surround!!
