Windows 7 shuts down my sound system after about 2 minutes. I can see the LED on my A-L speakers turn off. Any sound will wake it back up but if it's only a ping it doesn't wake fast enough for me to hear it. This didn't happen with this same hardware on Win2k (I skipped XP and Vista).
I went through the Advanced Power Settings but under Multimedia I don't have an option for sound.

It's a Realtek High Def Audio chip on my MSI motherboard.

I'd rather not disable power saving completely, so I'd like to find a way to prevent the sound system from going to sleep at all. Anyone know if that's possible? I'm assuming there's a registry setting but I have no idea where it would be.

Hello Bill.H,

How are these speakers connected to the PC, maybe with a USB connection? If they are go to device manager and find the root hub that the speakers are connected to by right clicking each of the USB root hubs and selecting properties. Then select the power tab and look under "Attached devices". Once you find the correct USB hub click the power management tab and uncheck "Allow the computer to turn off this device to save power"

Hope this helps

Thanks, everready, but they're connected via the speaker (out) jack on the motherboard with a 1/8" miniplug to the subwoofer. Subwoofer has its own AC power connection and the front speakers plug into the subwoofer.

Have you tried going to manufactures web site and getting the latest Windows 7 chipset driver for your motherboard. Never heard of power options shutting off speakers connected through regular speaker jacks.

Yes that was the first thing I did. I think it's shutting down the sound chip somehow, but that's only a guess.

It sounds like this motherboard is a bit on the old side. You used it way back with Win2k. Have you checked with Windows 7 compatability center Win 7 Compatibility Center to see if your motherboard wiil work properly with Windows 7.

Just a thought, hope it helps.

It's only 3 years old, and is compatible. If I disable all power savings everything works fine.
Thanks again.
