First, sorry for the loud background noise, my laptop is a dick! :D Otherwise, here is a video with controller sounds and male whispering about video games. I will play with my XBOX 360 and PlayStation 4 controllers and ramble a little bit about games and stuff. Enjoy and have a good night! :)
To listen while using other apps, switch the player to Picture-in-Picture (PiP) during playback — it keeps playing in a small floating window (the screen stays on).
To listen with the screen fully off, in-browser playback stops by YouTube's design. Open the video in the YouTube app to keep listening where background playback is supported (e.g. with YouTube Premium).
