the only reference I found to App_Server is the App_Server binary itself. Not sure if I should go down the path to change the source code and recompile...
I also found a file called SoundCards_AudioVolume.sh with some alusion to the Master mixer, but making changes there had no effect.
Would there perhaps be a way to delete the Master mixer and replace it with a new Master mixer that's an alias to PCM? I did find how to create an alias in asound.conf, I guess the question is how to delete the original master mixer?
I think that final solution should be somehow made, so that mixer name is device data for App_server or any other more suitable and convenient place... And probably this won't take much work to do...
Any opinions ?
