I'm having problems installing the sound card driver. The volume on my sound card is too low. Make sure your speakers are plugged into the sound card correctly.
Most sound cards come with more than one connector in the back.
You should verify the speaker is connected to the sound card's speaker or line-out connector. Also, make sure the speakers you're using are working properly. Be aware that systems with an integrated sound usually require powered speakers. If you're using non-powered speaker on such a system, the volume may be too low for you to hear. Check to make sure the volume is set correctly in Windows 9x.
