Problem with audio in Java application, Jubler

A problem I find somewhat strange. I've used Jubler to produce subtitle for a number of years. Like most subtitle editors, it has the facility to play the audio of just one selected single subtitle. I have a dual boot of Arch and Fedora 35 on an i7 computer. When I try to do this on Arch, it will only play about, say, the first 2 seconds of the subtitle; on Fedora 35 it will play the whole subtitle (as it has in all the years I've used it).

Terminal output Arch:

The Jubler-7.0.3.x86_64.appimage file in Fedora Home was copied from the Arch partiton on the same computer.

*************** Edit ****

I see it's using the AppImage packaged Java, so the Java information is maybe not so relevant. Something to do with access to /tmp on Arch; or is it the Arch audio-Java connection? There's no problem playing the video (on MPlayer) from a given subtitle onwards; it's just a problem with playing the audio (without video) of a single subtitle.

Re: Problem with audio in Java application, Jubler

I've discovered a difference in pavucontrol between Arch and Fedora.

Each time I try to play a subtitle in Arch it creates a new entry under Playback:

On Fedora, it creates an entry which disappears when the subtitle finishes playing:

I note the Arch entry isn't preceeded by "PipeWire".

When I try to play the sound for a subtitle, Jubler creates a .wav file in /tmp. This .wav file has the complete sound for the subtitle.

Jubler currently functioning correctly on Java on Arch,
