Public bug reported:
When an external microphone is connected to the analogue audio jack on the PC,
the internal speaker becomes unavailable and no audio can be heard.
It is not possible to select the internal analogue device in the Gnome
configuration settings.
However, the system works correctly with an external USB audio device.
