MIXT_MUTE mixer control type

Mute control MIXT_MUTE


This control type is derived from MIXT_ONOFF. The only difference is that it's tailored for mute controls. Value of 0 means unmuted and 1 means muted.

GUI mixers may want to implement dedicated widget for this control type. For example a speaker icon which has red cross above it when muted.

The MIXT_MUTE define was added to OSS between 4.0 and 4.1 versions. For this reason applications may need to use #ifdef MIXT_MUTE if they use this control type.
