Oops! It did come back. But I think it was because the above was necessary but not sufficient. I was playing a recording last night, and it kept losing sound, which could be tediously fixed as described above. Today, I replayed the file without loss of sound by doing this as well:
NOT ONLY:
Tools/Preferences/Audio/Output Module
choosing
ALSA audio output
instead of
default
BUT ALSO (at the same place in preferences)
Device:
As appropriate instead of Default
In my case the analog output instead of the digital or HDMI available on my motherboard
THEN the file played perfectly. I vaguely recall doing both the above when a DVD misplayed, and it then played from start to finish without troubles.
WHETHER the above two actions PERMANENTLY stops both the original problem (loss of sound after re-positioning using the progress bar) and loss of sound whilst playing normally remains to be seen. An issue with these problems is that you never know if the actions actually worked until there is another failure, in which case, they didn't work completely! If they make the issue go away for a long time, perhaps that's the best it gets!
I did, on the file mentioned, change the progress bar position both forwards and backwards more than a dozen times without loss of sound.
