OnOff Shim with Volumio

Support
1

Is there any chance of getting the OnOff shim to work with Volumio 2?

I have just installed my new board, but the installer warns about Volumio being unsupported.
It doesn’t work either.

I have a Pi 3, and a IQaudIO Pi-DAC+ mounted below the OnOff shim.

Try again now. You will receive a warning but you should be able to complete installation and get it working.

Perfect! Thanks. :-D

Guys can you clarify whether the on / off shim can be used in conjunction with Justboom DAC pHAT?
