Audio sync problems

[dodgymexican1]

I have just upgraded to a Senheisser Ambeo Mini soundbar. It has only one hdmi output which my Philips TV goes into. My 360 goes into my TV. There is no audio sync issues through my TV and it's apps. On the 360 no sync issues through the apps but when it comes to watching 'live' and 'recorded' TV the audio sync is completely out.

I have changed audio settings to PCM 5.1 (hdmi only) which seems to fix the issue. But sound is only output in PCM 2 channel which makes my soundbar useless as it outputs 12 channels Dolby atmos.

All apps on 360 output proper audio re Disney plus Dolby atmos etc etc.

Any suggestions?

Thanks

Hi there @dodgymexican1 

Thank you so much for your post and welcome back to the forums it's great to have you here. 

I am so sorry that you have faced this issue and thank you again for posting. Can I just confirm does this issue only occur when the sound bar is connected?

No there is a audio lag through the TV speakers too. If I change the 360 box to PCM there are no issues. All the apps on the 360 and through my TV there are no issues. It's just when I watch 'live tv' or recorded TV. Looking at other threads on here I am not the only one with this issue.

Good morning @dodgymexican1 

Thanks for coming back to the thread. 

Can you confirm if changing to PCM fixes both Live TV and recordings?

[dodgymexican1]

Yes it does. I have had to spend £160 on HD Fury 4K Arcana 18Gbps to fix the problem. I can now watch live TV and recorded TV in the source they were broadcast ie Dolby surround rather than down grade to PCM. Surely Virgin are working to fix this as there are loads of threads about this?
