Public bug reported:
I start playing movie in Firefox and there is no sound coming out. I open sound
configuration and change
"Output Device" from "HDMI / DispalyPort - Built in Audio" to "Headphones -
Built in Audio"
Sound starts to play and then after 5 seconds it stops again.
When I open sound configuration again, I can change "Output Device"
again and sound plays again for 5 seconds and then it is turned off.
I play sound using my display built in device connected through HDMI
cable and also using audio cable. Sound is not working through HDMI
cable. It is working using audio cable or headphones.
My expectation is, when I set output device to be audio cable - it will
not be changed to HDMI cable.
