Hi team,
I am running HiFiBerryOS on Pi 4 with an USB Topping E30.
I am looking for a method of setting the USB Topping E30 soundcard to the default soundcard (so it persists after Pi 4 reboots).
How can I "hard wire" the HiFiBerryOS setup to the USB card?
I tried:
1. changing the /asound.conf to card 1 instead of card 0, but this reverts after reboot.
2. changed /boot/config.txt to "dtoverlay=E30" but this gets overwritten after boot with an additional line of "dtoverlay=hifiberry-dac".

# aplay -l
