Fixing Computers

It can be very difficult to isolate the source of a sound system problem. Here are some troubleshooting steps to use to track an audio problem.

1.  Resource conflicts Use the Windows System Information Applet from the Accessories | Systems Tools menu to determine if there are any resource conflicts(IRQ, DMA, or I/O address) between the sound card and other devices. If a conflict exists, reassign the conflicting device or the sound card. The most common conflict is an IRQ.
2. Speakers Troubleshooting the speakers is a fairly straightforward process: Make sure the sound card is connected to the speakers and the correct cable is plugged into the correct jack on the sound card. Make sure the volume is turned up. Make sure the speaker wires are not crimped or broken and that all of the jacks are seated in the appropriate plugs.
3. Device drivers Sound cards are completely dependent on their software device drivers. Check the manufacturer's website for updated drivers.
4. EMF(Electromagnetic Field) Sound cards are very susceptible to EMF emissions from other devices and cards. Make sure the sound card is not placed too close to a disk drive or the power supply inside the system case.
