Updated to 20201230. Everything except Bluetooth dongle works fine. I was able to work around by putting the Raspi on top of the Bluetooth tower (using the handy usb 5v out) and accessing via a WIFI dongle. As luck would have it my DAC arrived today so I was able to connect to the tower via an RCA phono lead. Great job rern, thank you so much. Have a great New year.
