I've got a problem with HDMI audio. In the settings, I get two outputs, "Analog output" and "Analog Headphones". The first one is evidently the HDMI output, because when any sound is played, the TV makes clicking and buzzing sounds. I have tried various config.txt options to no avail. The same goes for changing between HDMI 0 and 1. LibreELEC, Raspbian and Raspbian with 64 bit kernel all work fine. Diagnostic output looks reasonable:
