•Problem: The volume sliders do not stay in place when some audio applications are used.

Solution: It is normal for the sliders to change position when certain sound applications are used. The applications are aware of the settings in the Volume Mixer window and are allowed to change the settings themselves. An example is the Windows Media Player.

to control the sound from within the application.

•Problem: The balance slider cannot completely mute one channel.

Solution: The control is designed to compensate for minor differences in balance and does not completely mute either channel.
