Windows 11 K-cast to TCL 4k TV

I play kodi on windows11, all is ok. I then use windows+k to cast to TCL 4k TV, it starts to play ok then the sound slows down as if it is in slow motion. is there any settings that should be checked?

Are the 2 devices connected to your router wirelessly, wired or a mixture of both?
If it’s wireless then are you using 2.4GHZ or 5GHZ?
Have you tried resetting the network on your PC to see if that helps? The PC will need to reboot to complete the network reset on you PC.

Thanks for your reply. Both connected wirelessly to 5GHZ, router reset several times to see if it would help with no effect. Tried one time connecting tv to router with ethernet cable which made no difference.

If you haven’t done already then you’ll need to try resetting the network on your PC itself. Here is a link on how to if you are unsure.
