Mute Check Box for MIDI Is Unavailable in Volume Control

• Microsoft Windows 95

SYMPTOMS

After you install DirectX 5.0, the Mute check box under MIDI in the Volume Control tool may be unavailable.

CAUSE

This behavior can occur if you are using a sound card with a Mixer chip. These chips are found on some models of Creative Technology Ltd. sound cards.

RESOLUTION

To mute musical instrument digital interface (MIDI) playback, in the Volume Control tool, move the Volume slider under MIDI all the way down.

MORE INFORMATION

The Mixer chip used on some Creative Technology Ltd. sound cards does not allow the MIDI volume to be muted. The Mute check box under MIDI is available when you use older drivers for these sound cards, but the drivers actually implement a virtual MIDI playback mute by turning the MIDI volume down to zero. With these sound cards, if MIDI playback is muted, and you attempt to record a MIDI file, no sound is recorded. However, it is possible to mute the playback volume of other devices (for example CD Audio) without affecting the volume of the recording from those devices.
