Snakeoil Firmware - 1.2.0 (Gear Isolation)

[realysm42]

I have made some form of progress;

1. I added an ALSA output device in SO
2. Tried to use LMS (instead of JRMC) 

and I have sound - this is a win of sorts, but even more frustrating as I would much rather use JRMC (and it's frankly much friendlier Jremote app that I purchased for my phone).

Any ideas on how I can set up an ALSA output device that JRMC can see?

And add JRMC back to the list of installable / controllable players in SO?

Any help massively appreciated here.
