since a few days I have the following problem in Ubuntu 16.04:
The application volume (as shown in
Sound settings > applications) of Firefox resets itself to about 50% any time an audio stream ends. I can set it to 100%, but as soon as the current audio (e.g. a video) ends it is automatically reset.
No other application is affected.
I've tried deleting
~/.config/pulse, as suggested in a simlar thread which hasn't helped.
