sorry about the late response.

No problem, everyone has a life and stuff to do.  Our audio dev may have some free time coming up and has some thoughts about how to handle the hints etc.  No doubt he can improve on my suggestion.  For the Windows stuff, I really need to speak to a Windows dev and see what they think about my changes.  Logs tend to indicate I'm on the right lines and I think selecting a mapping by number of channels rather than the channels we actually want is the wrong solution but I need to run it past some people to make sure.

Thanks for the sample, I'll do some testing with it and see what gives.

Audio devs seem to be even more in demand and rarer than other Kodi devs Hoping one day they will manage to look at this confirmed bug:
