I based my presumption based on past behavior (4.2-4.6, 5.0-5.1) and
seeing the logic of why a desktop user might have exclusive use - if
that user is first to use it. Before this, never tried to have another
user use it first.

I'll do that. But in the two cases so far, I had exited the T'bird after
reading the mail and expected that that should remove any locks and
close any open files.

I'll check this out too. The sound daemon is available, esound-0.2.36-3,
and I see a config file. I'll start checking the docs, configs, etc. to
see what I can discover.
