Thread: There's no sound after installing new hardware

If you installed any hardware or software immediately before the sound problem started, remove the recently added hardware or software. In the case of hardware, be sure to turn off the computer before removing it.

Compatibility issues with some hardware or applications could prevent the soundcard or its drivers from functioning smoothly. Check for sound after removing or uninstalling the new hardware/application.

If the sound comes back, it's likely to be a compatibility issue. Reinstall the drivers, then check the Web for updates and fixes for the sound card as well as the new hardware. Updating to the latest drivers and software from the manufacturer's Web site can help overcome many hardware/software issues.
