Title:
No audio output to Speakers when HDMI cable removed
Status in linux package in Ubuntu:
Confirmed
Bug description:
The Sound Settings dialog in Unity allows to switch between various
audio outputs.
If HDMI is selected and the cable removed the dialog shows that Speakers are
selected. But there is no audio. To actually output audio to speakers one needs
to click some other output ("Simultaneous output ...") and then again on
Speakers.
The expected behaviour would be to actually play audio on the speakers
without the need to switch forth and back.
