St32dvm board on a raspberry pi4b no rx audio

Hello,
I picked up a new raspberry pi4b to replace a raspberry pi3b.
I installed a new copy of pi-star and plugged in the st32dvm board.
Then I discovered the audio from the receiver wasn't coming through the board.
I put the st32dvm board back on the 3b and the receive audio worked fine
Would there be a setting on the pi4 that routes the audio path to another port?
I had a monitor plugged into one of the micro HDMI ports on the pi4.
Tnx

Audio doesnt route through the pi. Its a digital stream of 1s n 0s that ends up transmitted over RF by the mmdvm board.

Youd most prob. want to be looking at readjusting ur rx offset.
