One thought on “Raspberry PI comparison between latest models”
I did some testing using RPi4B’s hdmi0 and hdmi1. I normally use hdmi0 connected to a TV/monitor, and everything works well, especially when watching VLC, or youtube, etc.
However, when connected via hdmi1, there seems to be a cut-off in the audio, when playing video.
Described, the cut-off is like playing regular audio, then will drop the volume to 0, sustain it for about <1 second, then resume normal volume. This happens as frequent as about 3 occurrences per 5 second iterval.
I only have 1 rpi4, i dont know if this is localized to my own rpi4 alone, or inherent to all. OS is buster.
