Sky Glass HDMI Issues

[Sue.S]

I'm having issues with sky glass HDMI switching. I have Sky Q connected to HDMI 1, and PS 4 in port 3.

I introduced a soundbar to ARC port and it's gone all freaky on me. Everything worked fine for the past 2 days until this morning, switched on the tv and sound wouldn't work. Tried BT and that worked but with horrendous lipsync issue. Switched on the PS and the TV didn't automatically switch the Port 3, looked on the inputs and the tv is now not seeing the PS input. Baffled!!! Any advice I would appreciate it.  Thanks

Try rebooting everything. Turn all devices off at the wall for a minute then power the TV back on. Once it's booted up turn the other connected devices back on. This will re-establish the HDMI handshake and hopefully sort things out. You may need to check the audio output settings to make sure the ARC function is working.
