Sound on PS5 cutting out after playing a 4k Bluray

[Mikeni77]

HI All.

I have a 2019 Q60R TV and a PS5. I have an issue whereby when HDR is enabled on my TV and I watch a 4K bluray through my PS5 the sound will work fine while playing but as soon as I go back to the console main screen all sound cuts out.

I use a Samsuung Q70T soundbar.

Switching the HDMI port seems to temporarily fix it until the next time I watch a 4k bluray. The TV diagnostics say the HDMI cable is fine. 

Has anyone experienced this? I'm at a loss.

Hi Mikeni77, tried another hdmi cable?

[Mikeni77]

Yes, tried a brand new 4k high speed cable with no joy. I also tried a factory restore of both the TV and the soundbar with no change.

Just a bump for this. I'm still having this annoying issue.
