Xbox series X 4k 120hz bitstream audio keeps dropping

[TopBananaSr]

I have:

• xh9005 TV and Xbox series X
• the Xbox plugged into hdmi 4
• Earc turned on in hdmi 3 outputting to earc capable receiver
• 48gbps cables
• Correct settings applied to hdmi inputs

When setting spatial audio to be outputed to receiver, the sound keeps dropping.

When I select uncompressed audio formats, it seams ok

Given earc should pass through these audio formats, the sound drops every second.

Is this a bug with recent firmware earc update to this TV?

[TopBananaSr]

No update has solved this issue.

I tried various things recently.

I've tried:

 - toggling earc off and setting the audio to dolby digital from xbox to pass through, better results than atmos, but still drops

 - turning of pass through and getting tv to process audio which results into audio lag

The only thing that works is uncompressed audio set on xbox with 120hz set. 

I can also confirm that my friends PS5 he borrowed me was giving similar results when set to digital audio and playing a game 120hz.

It's definitely the tv 😞 .

I believe Sony is already working on an update for the 2020 TVs, but might be delayed since the 2021 models have just started releasing.

@Gshinert @TopBananaSr

Have either of you tried reaching out to the Sony support reps?

Thank you for the response Joe. I did reach out to Sony support to make a case and provide them the feedback. The tech was unaware of the issue and didn't have any knowledge articles to assist. I told him that this issue seems pretty widespread because a Google search for X900h 4k/120hz audio will result in discussions from forums like Reddit, CNET and even the official Sony forum about the issue and it impacting both PS5 and Xbox Series X. 

He said he sent my feedback upstream so hopefully that helps raise awareness this is an issue that needs patched. If you have any other suggestions or updates I'd love to hear from you because I'm excited about this TV and hoping it can run the features it's advertised to do.

Thanks again for the response and looking forward to hearing back from you and others as Sony hopefully works this out.

Hey Javad.mf, have you tried the steps mentioned on the thread? Hi Gshinert, Sony usually holds an investigation when an issue comes up, did you ask to be updated? Let us know what they say..

@Losdolfan

Have you tried the troubleshooting steps mentioned on this thread already?

[TopBananaSr]

That's pants!

They really need to sort this out.

I'll buy LG next time, they have had a better ride.
