I have gone full circle. So over in my bug we have deduced that I can make different volume mixers work or not work correctly by forcing different "model" parameters.
This is equivalent to saying that there no suitable "model" for my complete hardware - or in other words - volume controls I see and DACs that the netbook actually has are not correctly mapped. Because really a "model" is a set of definitions of DACs and outputs.
So I will try the patch, try the build from the PPA mentioned above, and try changing the "model" parameter and make a matrix of how these interact.
