Bug 249519: www/firefox audio/virtual_oss_ctl no longer showing TX in the bar

--- Comment #10 from Graham Perrin <grahamperrin at gmail.com> ---
I narrowed this down to two Firefox profiles – 'default' and 'test'.

With both profiles, the symptom (in virtual_oss_ctl) occurs in normal mode. 

With my default profile, the symptom also occurs in safe mode. 

With my test profile, the symptom does not occur in safe mode.

Not reproducible with a clean (refreshed) profile with media.cubeb.backend set
to oss.

What Firefox advanced preference (if any) might cause the symptom to occur in
safe mode?
