Troubleshooting a Sound Board
Traditionally, soundboards use many of the same chipsets and basic components, but because each board is designed a bit differently, it is very difficult for commercial diagnostic products to identify failed IC functions. For the most part, commercial and shareware diagnostics can only identify whether a brand-compatible board is responding or not. As a result, this chapter will take the sub-assembly replacement approach. When a soundboard is judged to be defective, it should be replaced outright. This part of the chapter reviews the problems and solutions for soundboards under both DOS and Windows. The following tips might help you nail down a sound problem most efficiently
- Check to see that your speakers are connected, powered, and turned on.
- Check that the speaker volume and sound card master volume are turned up.
- Check to see that the mixer volume and master volume are set properly.
- Be sure that the music or sound files) are installed properly.
- Check that all sound card and multimedia drivers are installed.
- Be sure that the drivers are up to date.
- Check for resource conflicts between the sound card and other devices in the system.
- Be sure that the sound card is selected and configured properly (especially for DOS apps.
- The sound device should be enabled and configured under CMOS (for sound functions incorporated on the motherboard.
