Rear is connected to a hifi-system, front to an

and subwoofer an active subwoofer.
How to control all these speakers at once ?
I would like to use my happauge remote
or my keyboard, but freevo allows only control
over one audio ctrl. Any ideas to control IGaine,
Digital, OGaine and Volume at once ?
This is a small mixer plugin for freevo.
the idea was to control more than one mixer slider at a time
and control sliders that are not present in the ossmixer
like IEC958 (digital output).
You can simply put the script in src/plugins
and activate it with:
plugin.activate('alsa_mixer').
Be sure to remove the old one with: plugin.remove('mixer').
You then need a config line like this:
MAJOR_AUDIO_CTRLS = ['Master','Surround','IEC958']
some problems:
- the volume in/decreases not so fast than in the original mixer
- in digital audio control in/decreasing isnt supported so it only
can mute the channel
Good luck.
Mike
