I have divided my multi-screen video into small 1minute chunks and uploaded it to info-beamer hosted. Mostly this works pretty well. My client at the museum says that there is consistent audio dropout i.e. silence at a number of the minute transitions. Does anyone have insight into what might improve the audio? Is there some audio switch to ffmpeg that I should have used while dividing up the video?

How do you play audio? Analog or HDMI? There has been a [bug in the Pi firmware](https://github.com/raspberrypi/firmware/issues/547) that has finally been fixed recently after 2 years that might cause that. The recent OS release 10 should include a fixed firmware for that.

One system uses HDMI, one uses the Analog.  
I don’t remember which one is the one with the audio problem but I will ask the client.

How should I update the device to OS10? It’s a beamer-hosted Pi in Iceland and I’m in the Czech Republic. My client doesn’t know much about linux, but could be instructed to unplug things if needed.
