Awesome update !
At first I had some issues with sound ressampling - some 5.1 sources were not being converted correctly compared with Jodi 16. But after some fiddling it stood ok.
In the end I was even able to wirelessly control osmc with my PS3 dualshock Controller (using the previously installed retropie configuration).
[EDIT] - some additional info as a friend of mine wasn't able to use the ps3 controller wirelessly, and some of you may have the same issue.
this is for a RPi 3/2:
In this example, dualshock was working with reptropie but NOT with osmc.
1 remove sixad dualshock support:
sudo apt-get remove sixad
2. configured ps3 torugh osmc new settings, input, controller, added playstation command, connected trough cable, configured buttons.
3 went into add-on and removed playstation controller.
4 back to the command line
(as I don't have the sixad installation source, have to re-install trough retropie):
5 revoke retorpie installation
manage packages / manage driver packages / ps3 controller (install from source)
[don't choose any other options. just exit]
7 follow the instructions previously posted here:
Now working wireless for both osmc and retorpie.
Probably there is a easier way, but as this one works, though to share it.
