On pc Debian x86-64 with master sources updated today, I could reproduce this. I noticed this log: warn:legacy.osl:19304:19304:slideshow/source/engine/animationnodes/animationaudionode.cxx:44: could not extract sound source URL/empty URL string
Created attachment 171826 [details] Simple reproducer example Let's turn this into something actionable... The original file has an m4a sound file, which is difficult to play on Windows (see bug 62408), but here something else must be going on, considering the confirmation from Debian. Turns out the original example uses a PP feature on the Carmina Burana clip, to shorten the played part. When applying that Trim feature on a simple wav file that can be played even on Windows, Impress does not recognize the media file as one so does not play it at all. Impress cannot trim multimedia files yet, but maybe we could transform this setting to effect duration setting.
