Public bug reported:
When switching from HDMI audio to internal speakers, the sound stops
working altogether. The only way to prevent this is to enter the
settings while still connected to HDMI and select "Speakers - Built in
audio" as the output. Disconnecting from HDMI without doing this stops
any audio playing through internal speakers or headphones (including the
speaker test in settings). It was expected that disconnecting a HDMI
output would automatically change the sound output to internal speakers.
Attempting to click "Speakers - Built in audio" when disconnected from
HDMI has no effect, the only way to remedy this is to reconnect the
device to HDMI and select the above output. This means if the device is
removed from HDMI and taken to another location, no sound can be used
until a HDMI output can be found and connected. Rebooting has mixed
effects, on one occasion a reboot restored the sound, however on all
others it does not. The test tones DID play during the debug process
however this is the only sounds I can get to play. The version of Ubuntu
is 18.04 LTS.
