speaker sound works for "music" cds, but not "game" cds. help!

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? (windows 98SE)

Does windows make a noise? Are these DOS games...? <img src="confused.gif" border="0">

Try resetting the configuration within the game to refind the soundcard.
Music CDs go through a seperate cable direct to the soundcard unlike game sounds which go through the pc itself,so the card is working but it may be configured incorrectly.

As you`ve not enabled replies I`ll respond to your private mailing to me here:
Depending on the game and its age there may be a "setup" or "configuration" section or seperate executable[mostly DOS games] that may enable you to choose the soundcard type and its IRQ/DMA settings.
Which games are you trying to play and does the soundcard work alright under windows i.e the media player etc ?
