My converted files are silent or certain software like Battlefield 2 and/or certain hardware no longer works correctly after installing MuvAudio. How can I fix this?

Some software and hardware devices have an incompatibility if your system has more than a few soundcards, hardware or software emulated (this number ranges on different systems). To fix this issue, when not using MuvAudio you will need to disable the MuvEnum Virtual Cable device in the Windows Device Manager. When you are ready to use MuvAudio, you will need to enable the MuvEnum Virtual Cable device. Steps for doing this are below.

To disable the MuvEnum Virtual Cable:

1.	On Windows XP, 2000, and 2003: Click Start, click Control Panel, click Performance and Maintenance, click System, click the Hardware tab, and click Device Manager. On Windows Vista: Click Start, click Control Panel, click Classic View on the left, double-click System, and click Device Manager.
2.	Double-click the Sound, video and game controllers listing.
3.	Right-click on the MuvEnum Virtual Cable device and click Disable.
4.	Disabling might take up to 1 minute. Once disabled, you should be able to use your software or hardware without issues.
