Sound out of sync/distorted XH90

[MrQwerty111]

Anyone have any HDMI sync problems? Have a 65” XH90 connected to a BT UHD box. All was fine.

However the last week sound (only use TV speakers) now crackles/distorts, and goes out of sync.

Switching inputs, switching TV off/on, gets it back in sync. This happens for recorded programs and live TV via the BT box.

However using the TV apps, Prime, Netflix etc everything is ok.

So tried a new HDMI lead, and different HDMI port and the same result.

So I presumed it was the BT box, however just received a new BT box and it’s the same....

So is the TV broke? Why are apps ok, only the HDMI sockets broke?

Anyone anymore help please
Thanks

If you have tunein installed on the TV uninstall it and power the TV off for a while, seems to have resolved the issue for a lot of us

I have uninstalled TuneIn as the others on the forum have suggested and so far all seems ok no sound issues here's keeping fingers crossed

I have this exact same problem, using HDMI input for PS4 and TV speakers the sound is very laggy and out of sync. It only started after the HDMI 2.1 update. I've only had the TV one day so I might return it for a refund if Sony don't fix this issue pronto.

Maybe try to read this thread. Is there a solution:

UNNINSTAL TUNEIN FROM APPS IN YOUR TV!

Now maybe people will see. Can Any1 mark as solution?

Thank you for providing a solution such a shame Sony have not been as helpful on the forum

Similar issue with a KD49XH9505. Doesn't do it all the time but when it does not only are HDMI input items such as Sky TV and blue ray player giving the sync and distortion problems, but also watching terrestrial TV the sound is distorted, though no sync issues there. Hoping and praying the suggested deletion of the tunein app works as I have given my local supplier my notice of intention to return it for a full refund within 30 days. To give them their due they did immediately replace my original TV with another but the problem persisted on both. Using only TV speakers but the distortion also carried over to blue tooth headphones.

I uninstalled tunein at around midnight last night, have had no issues since then, tv has been on most of the day,

Quick update. 

Having uninstalled tunein this morning my XH90 has been fine all day, no audio issues whatsoever, this was a very unexpected and random fix to this very annoying issue, fingers crossed this is the end of it all, I can't thank the guy who suggested this fix enough! Hopefully we can all enjoy our TVs now!

How’s everyone’s TV since Tune In uninstall? Mines ok since for nearly 2 days off and on now?
