My RPi 3 melted , so I replaced with a RPi 4
I refitted the Allo Digione card and loaded Roipeee xl
I thought I would check out USB via my Audiolab M-DAC. I get a rhythmic ticking noise UGH
Switch to Digione no problems. Disabled the HAT same problem ,
Can I run USB and the Digione on the same RPi and switch between the 2 zones in Roon ?
Anyone any ideas ?
