Is it feasible to remove "Center" , "LFE", "Wave Cetner" and "Wave LFE" Playback Volume control ?
or add a bitmap to disable the creation of those controls
Anyone know whether this patch has any side effect for the user with Live Drive
The side-effect is that opening surround51 would spew annoying error messages as you've seen. It should return an error without much complaint.
I'm not sure what is the best way to solve it. Defining another conf such as EMU10K1-4ch.conf would be an option, but it's not elegant...
