sleep mode causes sound issues

Greetings to all of you,

I've used Windows 7 RC for 3 days now, and quite love it actually. But, from the moment I installed it, I had a weird issue. Whenever my computer (laptop/notebook (whatever you call it where you're from)) goes into sleep mode, (as it was configured by default after xx minutes (can't remember)), as soon as I wake it up, it appears to have "lost" the sound driver, as it says: "no audio output device is installed". But when I restart, I can use audio speakers with no problem.

(took a while to find out problem was sleep mode, because with laptop/notebook I do --> close lid, unplug power cable -->move somewhere --> plug in power cable --> leave it for 30 minutes...... )

Summary, computer goes to sleep mode --> wake up --> audio driver is unavailable --> no sound output until restart.

I just installed Windows 7 RC ed. on a laptop and PC. Not only when it goes to sleep, but also on Hibernation, it would be safe to say that any form of shutdown that is not a complete SHUTDOWN tend to bring up this problem. I don't find the driver dissapeared. Only the sound muted, as I can still manage to display the sound properties and watch that little green bar activate whenever a sound emerges from the software. Simply, the sound is muted, but no I don't see any drivers dissapearing. It's bad on my laptop cause I frequently put her to sleep. I gotta restart it if I wanna hear some monster slashin on my WOW game.

I forgot to mention. My laptop has 64-bit version 7100. And my PC 32-bit version 7100. So it must be a basic problem on the OS itself. Windows drivers? I don't think so. I had to download the sound drivers on my PC, as I have a Creative X-Fi Platinum, and Windows couldn't find the drivers itself. I forced the installation of the drivers with Creative Labs. It must be something simple causing this problem. Hope it will get fixed on an update. Just keep sending feedbacks.

It's happened once to me after waking from S3 sleep mode.
To restore the sounds without rebooting, I restarted the Windows Audio Endpoint Builder service, which also restarted the Windows Audio and the Creative Audio services.
