My laptop has a 2560 x 1440 built-in display. I usually connect the laptop to a 27-inch 2560 x 1440 external monitor via HDMI.
I use it as Single Display with the external monitor only.
The following happens quite frequently:
When disconnecting the HDMI, using the laptop without the external monitor and then connecting back again, I see that online videos do not play as soon as I turn “on” the volume in the online service volume bar. Only when muting the volume, the video then plays.
See this quite explanatory video:
