I use a television as my main monitor on Windows 10 Pro and connect to it via HDMI. This works fine for the most part, however if I turn the TV off for more than a couple minutes, when I turn it back on, Windows doesn't detect its speakers.

  • I have a workaround: Sound Control Panel > Sounds tab (see screenshot), as just opening it, without doing anything, makes Windows detect the speakers.
  • Volume Up/Down/Mute buttons, Volume Mixer panel, and Settings > Sound panel do nothing

Since it's such a trivial thing that makes Windows detect the speakers (possibly cache invalidation?), is there some way to automate this?

This problem went away with later Windows updates and has not surfaced again that I've noticed. Therefore the solution appears to be "do nothing".
