    I have also noticed small clicks/pops in HDMI audio in Kodi, not on LibreELEC but using a custom build of Debian Buster with 5.3 kernel.

    If the CPUfreq scaling governor is set to "performance" it doesn't happen for me.

    If the governor is the default "ondemand" I hear the clicks. So I suspect it's related to CPUfreq switching frequencies.

    KOPRajs and butterkitty on the mainline kernel, you could try running (as root)

    1. echo "performance" > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor
    2. echo "performance" > /sys/devices/system/cpu/cpufreq/policy4/scaling_governor

    and then test HDMI audio. It'd be interesting to see if that fixes the issue.
