I haven't changed anything audio management related since installing elementary OS 0.3.2, but I have to refresh Youtube videos (or pages they are embedded in) in Firefox to get them to play.
This isn't a Flash-only thing because other programs do it too. if I use Clementine and open a game or similar sound producing application, Clementine moves to the next song and throws the following error:
"pa_stream_writeable_size() failed: Connection Terminated"
About the time this error shows up, apport reports that Pulseaudio Sound system KDE Routing Policy has closed unexpectedly.
Anyone else have this issue? Would reinstalling elementary OS fix it?
