Computer sleeps during Audio playback
I have a problem when trying to playback music on music.youtube.com, when playing video Firefox inhibits sleep as expected, however if i switch over to audio only it does not. I am not sure if this is expected behavior or not, but I find several post on the internet of people having the same problems with Spotify. All Chromium based browsers inhibit sleep when playing audio.
I was just wondering if there was an obvious setting that I have missed, because I can see why you might not want to do this in the case of adverts that play audio etc, but what if, like me, you actually want to use this feature.
I am running Manjaro, with KDE Plasma 5.26.5 (6.2.0-1 Kernel).
