I have a Gateway M405 laptop and I can't get the sound to work. Every time I try to open volume control I get an error message that says "There are no active mixer devices available. To install mixer devices, go to Control Panel, click Printers and Other Hardware, and then Add Hardware." When I try to Add Hardware though it says that there is no available hardware to install. I have Windows XP Professional version 5.1.2600 with a 1.5GHz Intel Pentium M Processor version x86 Family 6 Model 13 Stepping 6 with a 1498 MHZ speed. If anyone has any suggestions for me, they would be greatly appreciated.

Is this a new problem? Were things working OK previously? Any new hardware or software?

If this is a new problem try a System Restore to a point prior to the problem:

start > All Programs > Accessories > System Tools > System Restore


Otherwise see if installing this driver helps:

Check device mgr - if all are sound devices are working properly - go to start>control panel>admin tools>services - scroll down to Windows audio. Make sure it is set to Automatic and all dependant programs are enabled.

Under the recovery tab select restart service for the 1st, 2nd and 3rd failures.

Worked for me....

hmm. happened to me that day. but all it needed was a system restart. tried safe mode yet?
