Bravia xh9005 sound sync problem with Humax hdr-1100s

[Rayw53]

My nice new TV is having sound synchronization issues when playing my Humax Freesat box. Starts off ok when playing, then after about 10 mins the sound is out of sync. Tried forcing a sync from the TV help menu, hdmi device, it works to fix for a while then goes out of sync again.

Any ideas

Have you tried enabling Enhanced HDMI signal format in the settings?

Hmmm! I haven't tried that setting yet. To be honest I haven't seen this setting for hdmi inputs. I'll give it a go.

The hdmi setting was on enhanced, tried on standard, neither fixed the issue.

I'm starting to think I need to upgrade my Humax box, even though it's only 3 years old.

I think it is not a box problem i got xh92 one month.

I got problem with sound on HDMI. Every cable I tried doing same.
I play game or connect laptop on HDMI after some time sound start crackling little (like robotic sound) and after this sound start sync out, every minute more and more. I tried different hdmi on TV and its same. When i reset by button on remote, its go back to normal but only for moment. Sometimes longer, Sometimes quicker when the sound start sync out. I got soundbar connected to tv by optical and its the same.

That's exactly what I am getting. I have a Roku device on another TV , think I will try that on the Sony TV to see if it has the same sound issues. 

Thanks for your comments.

I tried 2 laptops, xbox one and everything is same. Different setups  and nothing better.

Hi

What I've heard about this is that Sony is investigating the issue and recommends unplugging the TV from the mains for a minute to refresh the system.

Do you seem to notice the issue only on Game mode? I've read a post by a user who noticed that so I thought I'd ask.

The sound sync / distortion seems to be happening on most devices input through hdmi ports. Mine was from a Humax Freesat pvr . Unplugging to reset works for a while , then the sound starts going out of sync again after about 10 mins, and gets progressively worse.

I've noticed it seems to happen with 1080p sources. My Xbox one has the issue intermittently. Also when I load a game at 1080p on my PC the same issue is present. Some users have said that the latest HDMI 2.1 update fixes the sound sync issues.
