Bose soundbar 900 interference issues

I got a Bose soundbar 900 and I am having an issue where the sound will sometimes just go fuzzy on the voices and noises, they are ok and can be heard fine but you can hear a trailing fuzzy noise on all sounds. It can last seconds or minutes. I tried all their troubleshooting steps and none worked, I sent it back to Bose and they tested it and reported that they could not find an issue. I was on to them again yesterday and tried some more things but still no luck.
Would anyone have any idea on how to fix this.

Setup is as follows:
- Bose soundbar 900
- Connected with HDMI earc ports
- Sometimes use Sony UBP-X700 (Issue occurs more often when using this than just watching Netflix on TV with soundbar but still happens quite often when watching Netflix)

Steps I have tried are:
- Changing HDMI cables
- Turning off all smart lights and devices around the tv and soundbar in case of interference
- Turning off the CEC on soundbar unplugging it waiting a minute plugging back in and turning back on CEC
- And just playing with different settings.

I could attach an mp3 of the issue if you need to hear it.

If anyone has any idea on how to fix this issue it would be greatly appreciated.
