Bug#749187: pulseaudio: When switching from HDMI to Analog output, sometimes no sound is heard

[Michael Meier]

Package: pulseaudio
Version: 5.0-2
Severity: important

When in pulse audio the output device is set to the HDMI connection of my laptop, and later on I unplug the HDMI cable and switch to "analog stereo duplex" or "analog stereo output" (using pavucontrol or the kde media center)
most of the time I wont hear any sound (sometimes it works, but mostly not).

In pavucontrol I can see how in the output devices tab, a "built-in audio analog stereo" device is added, but the HDMI devices stays, and all sound continues to get output on this one.
Opening and closing applications doesn't help.
The only way I manage to get the internal speakers of the laptop working again is a system restart.
There are no message in system.log or any other log file I could find.
