@Fourdee - genial!!!
Just did it also in my DietPi installation. It works.
Roon Community will love you. The super light DietPi now 384/32 and DSD compatible - this is ACHIEVEMENT!
Would be great if you could add this to your next release dietpi-config options. I will already now report this achievement in Roon Community forum for members to start using and testing.
One more thing you could simply fix is the issue of AirPlay and Squeeze coexistence on same RPI.
See a lot of discussion on it in your forum.

I found the key "-C " in Squeezelite v1.8 settings that allows to release audio card if not used by Squeezelite.
Squeezelite v1.8, Copyright 2012-2015 Adrian Smith, 2015-2016 Ralph Irving.
Usage: squeezelite [options]
-C Close output device when idle after timeout seconds, default is to keep it open while player is ‘on’
Unfortunately, the Squeezelite version you have added to DietPi is different and missing this -C key.
However, in the moode I managed to use this key successfully “-C 5” with 5 seconds release, and I had the Room, AirPlay, and Squeezelite all three coexisting & working perfectly on the same RPI.
Please have a look, I hope you can change the Squeezelite to v1.8 also on DietPi?
