Hi Mike / hi Simon,
the fix for the wolfson/cirrus logic card in the current version of Max2Play (version 2.37) uses a newer Kernel that fits the latest Max2Play-Image and uses a renamed Device Tree Overlay for the card.
This definitly works when using the latest Max2Play-Image -> Install Wolfson-Card on Raspberry Settings Tab -> Reboot -> choose Card in Audioplayer Tab (advanced Settings) and set prefered Audio-Output on Raspberry Settings Tab.
Older Max2Play-Images should still work, as the Bugfix just targets the latest Max2Play-Image based on Kernel 4.4.y
@Mike: After installing the Wolfson-Card with the Kernelchange, the change of the installed soundcard to “none” doesn’t change the Kernel back to the original one. But it removes the DTOverlay entry to load the card on boot. If your card won’t work after the next reboot, make sure to select it again.
All the Best
