Vista alt tab sound issues

Hey,

Whenever i'm gaming while being on ventrilo and i alt-tab(windows key) back to deskptop my sound either gets screwed up for the people listening to me on vent(so my outbound) or all my own sound goes crazy. 90% of the times this happens and i'm not sure what to do about this as when it's just my outbound messing up it seems to get fixed by reconnecting to ventrilo but when all my own sound is screwed i sometimes have to reboot to get it working normally again. The best way i can describe what happens is that my sound get very metalic, sharp and distorted. Is this a known issue with vista and my sound card (xfi xtreme notebook audio)? My gf has the exact same laptop as me and she also has the same issue, she's had it alt tabbing out of her bookkeeping program back to desktop(this takes ventrilo out of the equation). And she has it also under the same circumstances as the ones i listed above.

Thnx for your time

*update* I managed to narrow the problem down to the xfi xtreme notebook audio card. When i switch to the onboard realtec i can't duplicate the issues. The problem is everything sounds so much better with the xfi card when it's working properly that i dread going back to the realtec full-time. Are there no other xfi notebook card owners out there that can tell me if they can alt-tab out of 3-D applications without messed up sound?

 

The only thing I can suggest is to UNinstall the Realtec driver, and to also play with the creative driver to get as close as possible to just the driver and no other extras. It is known the Creative drivers under vista are poor, and if the m9750 has an uneven power level to the express card slot you are going to need to experiment. That is also another thing to try: doing it with and with out the batery installed, and also to do it on battery power alone.

The thing for me is that once these issues start with sound drivers, they are really hard to get rid of (i think it has something to do with direct sound). Either way do whatever you can, maybe even reinstall the OS, or dual boot with XP, but that is the best I can offer.

Cheers!

 

Thnx so much for your reply. I've tried everything you listed short of reinstalling my OS. Sadly the issue still isn't resolved I did get a reply with some interesting info from some other place though. I'll paste it here(it's not from this forum) so others can comment or maybe understand their issues better.
Thnx to Btarunr for taking the time to adress my issue :

So basicly loads of people must be having this issue who use +EAX 3.0 cards. One would expect this issue to get a fix in the near future(don't hate for me staying positive )!

 

You may also want to make sure you have the latest driver for the sound card.
If anything else you may just have to wait for a bit, I've never had an issue with Creative sound cards and ventilo before.
