i've gone through all the "system" screens, the sound screens, the multimedia screens and i can't figure it out. the speaker sounds were gone completely until i saw that the little yellow speaker sign at the bottom of the screen on the bar was muted. so i fixed that, then i was able to play music cds, but my son's games will not work. what do i need to do. all the pc speaker, microphone, line in , cd audio, midi, wave, volumn controls are all on (none muted and volumn all the way up). every where i have found volumn controls they are all on. can anyone tell me what to do?
