GPMDP Issues

Hi

My HA is 0.60 with python 3.6. I have just set up GPMDP (Google Play Music Desktop Player) which is running on my desktop PC on a different network. My HA is installed on my rpi…

I can get the media player displayed on my frontend but when I try and play any music I get the following errors:

2017-12-26 23:07:23 ERROR (MainThread) [homeassistant.core] Error doing job: Task exception was never retrieved

    raise NotImplementedError()
NotImplementedError

All I want is to play some music on my desktop or linux which is on a different network to my HA (installed on my rpi).

Has anyone got any idea on how I can achieve this or resolve the above errors?

Thanks.
