two days ago i started up my computer and BAM. no audio. i open up the volume control and it says "There are no active mixer devices available. To install mixer devices, go to Control Panel click Printers and other Hardware and the click Add Hardware". so i go into my device list thinking something was wrong with my drivers but there everything was recorded as fine. i reinstalled the realtek drivers off their website, reinstalled direct x but it is still not working. i made sure it wasnt disabled and i checked in my bios (though there was no option to disable/enable audio devices) i also tried the services.msc thing with making sure it runs automatic and also attempting to start it. and when i start it in services.msc an error pops up and says "could not start the Windows audio service on local computer error 0xc0000096" i am also using a plantronics gamecom pro1 headset (dsp chip) if that matters. plz help me troubleshoot this problem. thx in advanced.
