Bug#882142: upgrade from 11.1-1 to 11.1-2 breaks audio support in Firefox

[Harald Dunkel]

Package: libpulse0
Version: 11.1-2

After the upgrade to version 11.1-2 

	[UPGRADE] libpulse0:amd64 11.1-1 -> 11.1-2
	[UPGRADE] libpulsedsp:amd64 11.1-1 -> 11.1-2
	[UPGRADE] pulseaudio:amd64 11.1-1 -> 11.1-2
	[UPGRADE] pulseaudio-utils:amd64 11.1-1 -> 11.1-2

Firefox lost audio support. There is just a notification
line saying "To play audio, you may need to install the 
required PulseAudio software". 

Next to pulseaudio no other packages have been changed. 
A downgrade back to testing does not resolve the problem.

Firefox is version 56.0-2 or 57.0-1.
