[Alsa-xmms-user] Need to control multiple mixer devices

[Jim Faulkner]

I have a SB Live which is connected via digital out to my Cambridge
Soundworks DTT2500.  I am using Linux 2.4.21 and Alsa 0.9.5.

The only mixer controls that work for me are "Wave" and "Wave Surround".
The former controls my front speakers, and the latter controls my rear
speakers.  Neither "Master" nor "PCM" do anything on my machine.

I would like to have xmms control multiple mixers with its volume control.
eg I would like to have both "Wave" and "Wave Surround" controlled by XMMS
so that my front speakers are always the same volume as my rear speakers.

Is it possible to do this with alsa-xmms?

If not, is it possible to map multiple mixer controls to one mixer control
in ALSA?

thanks for any help,
Jim Faulkner
