OpenELEC Testbuilds for RaspberryPi Part 2

Now, I'm seeing the initial frames of the video and hearing the audio (about 1/10th of a seconds worth), THEN black screen/silence until the 3.2 seconds has elapsed, at which point the video/audio starts again.

It's not a huge issue, but it would probably be better if the video & audio didn't start, stop, and then start again while changing refresh rate.

Unfortunately video playback and HDMI mode change are not really synchronised. I believe when the first video frame has been submitted that the GUI gets notified of the resolution / framerate, and then the HDMI mode change happens soon after. Similarly the video/audio happens soon after.
I'm not aware of anything that has changed in that area, but there's nothing to stop it behaving in the way you describe.

You might want to experiment with setting the GUI mode to 1080p24 (or whatever your predominant video rate is) and enabling receiver keep-alive.
In theory you should have no HDMI switching delay for most videos. I'm not sure if the 23.976 vs 24 fps will still cause a switch (although that may be avoidable).

I can investigate if there's some way to detect if that the pause/unpause mode is enabled, and then skip the initial play+pause.
