Audio Config I2S settings

[Woodroww]

Hi - I have a Pi 4B (8 gb) with Allo digione Signature hat - running Moode. Controlled by LMS
Just wondering about the options in Audio Config - I2S Audio Device - what is DT Overlay option ?

For what it is worth, I have a Pi3B+ based player that uses a Hifiberry+ based proprietary card. It's a Magna Mano ultra. Normally I use(d) it over AES-EBU.

Just this afternoon I tried the I2S connection with my DAC. It just worked, both PCM and DSD.

No fiddling...
