SPARC: Audio Mixer

The audio mixer driver now enables multiple applications to simultaneously play and record audio. This new enhancement supersedes the previous capability, which only supported a single play application and a single record application.

The audio mixing function is turned on by default and can be turned off as well as on using the new mixerctl(1)utility, or through other methods described in the man page audiocs 7D.

When running SunVTS^TM the mixing function should be disabled.

In addition, CDE 1.4 now includes a new GUI tool,sdtaudiocontrol, that supersedes audiocontrol. sdtaudiocontrol uses the features of the audio mixer and provides:

• A graphical method to enable and disable the audio mixer

• Volume and balance control for each application

• Volume and balance control for mixed audio when the audio mixer is enabled

• Controls enabling and disabling the input and output ports

• Display of status information on each application using audio and on the audio hardware

For more information, see the man pages audiocs(7D), audio_support(7I), and mixer(7I).
