Public bug reported:
Binary package hint: pulseaudio
If I use epiphany or Firefox while I have a system-wide instance of
PulseAudio running, I experience normal performance...until I try to
visit a site which uses Flash and wants to play sound.
At that point, Firefox or Epiphany core dump, and if they were running
in terminal, they print this:
$ epiphany

My user is in pulse-rt. This is with the libflashplayer unofficial
pulseaudio package installed.
If I set the environment variable FLASH_FORCE_PULSEAUDIO to 1 and run it, the
behavior changes:
$ epiphany

If I set the environment variable FLASH_AUDIODEBUG to 1 as well, it...functions
perfectly, and outputs thus:
