The bit about "Dummy Output" doesn't look right. Try to right-click on
the sound icon at the top, then select "Sound Preferences", go to the
"Output" tab and check that the device in the option list at the top and
the connector in the drop-down at the bottom are correct. Mine currently
has "Internal Audio Analog Stereo" for the device and "Analog Output /
Amplifier" for the connector.
