Public bug reported:
If I plug in a audio capable HDMI monitor, I used to change the audio output
device to HDMI using the regular audio settings dialogue. For some weeks, this
device has disappeared. I can only chose the internal speakers for audio output.
I’m not quite sure but this bug could have appeared after dist-upgrading to
14.04.
Which additional information do you need to fix this bug?
