I was aware that also rng-tools could help, but as I was not aware that the PI has a hardware random number generator (which is required for rng-tools afaik) I've chosen haveged.
As I now learned that the Pi really has a hardware integrated random generator, I also would prefer the rng-tools.
Even if it's not really important as we know solutions/workarounds for this issue, I'm also puzzling regarding the question what generates enough entropy on your system, whereas mine don't. Which additional hardware do you have attached to the Pi?
In my case, it's completely headless with only SDCard, Justboom Amp Zero and a rotary switch. With this combination I can reproduce the issue on a Pi Zero and a Pi 3a+.
I checked just now with moOde 5.3.1 on an RPi3B+, headless, WiFi client mode, I2S HiFiBerry DAC+ Pro. No haveged, no rng-tools. The moodeutl -i output below shows what's enabled and what's not.
Rebooted. Took about a minute for the system to respond to an ssh login request and for the UI to appear. Then I could immediately start playing a radio stream.
Code:
pi@moodeLR:~ $ dmesg|grep rng
