When using Zoom etc in the kitchen, I plug the TV into the laptop via an
HDMI cable. Not only for the bigger picture, but to use the sound system
too.

But the cable is not only untidy but a trip hazard too.

So bought a MiraScreen HDMI dongle. Which powers up nicely from a USB
socket on the TV. Mirrors the laptop pic and sound on the TV via Wi-Fi.

After quite a bit of faffing around got it working OK.

But can't find a way of muting the laptop internal speakers. The laptop
sound system does not recognise MiraScreen as an alternative to them -
unlike the HDMI cable which showed the TV sound system, so you could
select the one you wanted.

Any suggestions other than a dummy jack into the headphone socket?

Stick a dummy jackplug in.
