Quite possibly. Andrew's good idea of two Pis with their UARTs connected so you've a serial console might actually give useful information when it freezes rather than all this guesswork. > Your suggestion to use a HDMI adaptor has merit and in fact was one > solution that I looked at very early on in the design.

You don't make it easy, do you. :-) The Zero can have its audio out jack restored if that would give a separate playback to HDMI. https://learn.adafruit.com/introducing-the-raspberry-pi-zero/audio-outputs Or there's investigating playing one MP3 on HDMI's left channel and another on its right. Staff would just dish up two MP3s without caring. -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy -- Next meeting: Bournemouth, Tuesday, 2017-02-07 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:[email protected] / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR
