When i click on volume control it says 'no mixer devices' or something along those lines. I dont know what this means but my sound worked fine yesterday and I think I was getting those errors then also but now for some reason sound has stopped working altogether. I don't know what to do I don't know if I need to reinstall my sound card or what? I dont think I still have the disc. I got new speakers and they didnt come with a disc so Im really confused. What do i do? Im going crazy the only solution I can think of is buying a new computer but I cant really afford that. Please someone help me..........please!!!!!!!!.
