I am trying to get the IAN CANADA FIFOPI ULTIMATE Reclocker Module (HAT) with RPi3B+ working with Volumio. I used several device selections in the output menu (from Generic I2S to HiFiBerry Digi+ and HiFiBerry DAC) but It keeps producing mono sound. The right channel is missing, and the left channel is played back on both speakers. If i use another input of my DAC, the sound is as it should be. The same if I install RoPieeeXL (ROON) on the RPi SD card. So it must be a software compatibility issue. Does anyone know which driver I should use in Volumio? Or is a dedicated FIFOPI driver in the development pipeline? Thanks inadvance!
