I wasn’t quite sure where to post this - please move if needed! 
I just purchased a Topping E30 DAC/L30 amp stack (seems like a great little combination so far very impressed with my HD600’s!) but when I first turn the E30 DAC on connected to the Raspberry Pi 4 running Ropieee it displays flashing DSD 45.15 then 22.57 randomly - does anyone else have this with a Topping DAC and Pi combination? Once I start a track playing through Roon it locks on to whatever and all is very ok from then on. Just wondered if it’s a faulty E30 or a recognised characteristic of the Raspberry Pi 4 with some DACs?
PS. I have never played any DSD through the Pi (or anywhere for that matter!)
