HiFiBerry sends signal even when nothing is playing after update


I have RPi4 with HiFiBerry Digi+ Pro and I have just downloaded new OS version (hifiberryos-20210531-pi4.img) from website.

Now, when my RPi boots, it instantly sends signal on coax out, even when it is complete silence. This renders RME ADI-2 DAC input auto-select feature useless. Before updating when I was not playing anything in Roon, signal was off and my RME automatically switched to optical in and back to coax when I used Roon. Now it is stuck with coax in, as it constantly detects signal from coax. No matter if it plays music or not.

I have briefly checked software and installed RoPieee - problem was gone. When I installed HiFiBerryOs back, it instantly sends signal after boot.

Can you fix it, please?
