21.04 - Sound issues (Analog Stereo Duplex VS Digital Stereo (HDMI) Output + analog stereo input)

[Daniel LaSalle]

Using 21.04-latest on a laptop that's main function is to listen to TV and watch videos.

The laptop is constantly plugged via HDMI into a 65" LCD screen and our goal is to use the sound/speakers of the TV and not of the laptop.

The problem is not only two folds but it's also random.

After I did a full OS reinstall and left the settings to bare minimum(vanilla), I have selected a RANDOM screensaver as default alongside "Digital Stereo HDMI Output + analog Stereo Input" and when I play a video, sound works as expected. Also, there is no "UI defects" when selecting the hardware audio output (More on that "defect" later....).

So all is well.

If, for example, I leave the laptop idle and the(any? still not sure about that....) screensaver kicks in it will happen SOMETIMES that 1. the default hardware audio gets defaulted back to "Analog Stereo Duplex" (AKA the laptop speakers), the sound volume goes back to 100% (Because it doesn't make sense from a user's perspective when watching a movie that the sound only is set to 100%, it needs to be set to 160% or 200% for the experience to be good(note to self: maybe I should also open another bug/annoyance for that))

Also, when restoring the session and that the volume went back to 100% and that the default hardware output felt back to analog stereo duplex ON TOP of that it seems there is a UI defect (look at the picture I will be posting after this).

Hope this is clear.... If not, thanks for letting me know.
