i've posted this on Falcon, but I do not have a fix:
What appears to be a random occurrence I loose the audio output from the Pi. I'm using a 3B+ with the latest software. ALL OF MY AUDIO FILES ARE VIDEOS. It might go for hours before I get a failure, and it is difficult to test which sequence fails because the playlist keeps on going, flashing the light etc. The logs don't show any thing useful, and the captain provide a script to continuously run the audio part of the playlist (but the script appears not to work right).
Anyway, I check all the file names for caps in the extension etc....no luck! Have any of you experienced the same thing?
