Title: HDMI audio device disappears and is unavailble after several minutes of not being used Status in pulseaudio package in Ubuntu: Incomplete Bug description: On system boot both of my audio devices are selectable and useable. After around 10 minutes the HDMI device just disappears and cannot be selected as output in either the task bar audio applet or in Kstart>system settings>audio(either devices or advanced tab). In the devices tab a device called Dummy output is displayed and in the advanced tab the HDMI device is shown, in this case GP107GL, with the profile in the dropdown box underneath it displaying off with no ability to switch it to on. If I go to pulse volume control>configuration i am able to select the HDMI device and the system will use it. If I play a 2 hour movie after this and then turn off the media player the HDMI device will once again disappear after about 10 minutes. When I ran ubuntu-bug <pulseaudio PID> the system identified the HDMI device and switched to it (it is set as default) and has remained accessable for 15 minutes now. I am running the NVIDIA 450 driver package. If I run Kubuntu 20.10 a similar problem occurs except the the profile of the device is somehow damaged but by selecting any speaker setup (profile), audio returns.
