Wrong installation ? What's your system, Windows 7 or 10 ?
If yes, do the following:
WINDOWS 7
1º - Uninstall your Realtek driver and any audio software that works together.
2º - Restart the PC. When the first screen of the BIOS appears, repeatedly press the F8 key until the security options appear.
3º - After they appear on the screen, choose option 7 by pressing the 7 or F7 keys (Disable Driver Signature Imposition).
4º - After the system is started, simply install the driver package contained in the file you downloaded, then install the Creative Sound Blaster X-Fi MB5 suite (I
recommend extracting all the contents of the compressed file).
5º - Restart the PC and then just enjoy the new audio experience in music and games.

And restart the PC.
3º - After the system is started, simply install the driver package contained in the file you downloaded, then install the Creative Sound Blaster X-Fi MB5 suite (I
