SONY KD-65XH9005 SONOS ARC & XBOX SERIES X Issues

[kinger251285]

I recently purchased a sonos arc which arrived last week, setup as per the sonos instructions and was all working fine.

However i have started encountering issues with the sound just randomly dropping out. This can be when watching TV or using one of the android apps on the tv (Disney +). Also when the xbox series X is set to output dolby atmos the sound drops every few seconds. Sometimes when the tv is first turned on then sound does not come through the soundbar. To rectify the TV audio i have to change the output from Audio System to TV Speakers and then back again. This however does not stop the sound dropping randomly again or the Xbox Issue.

I am unsure which device is the problem, whether it is the soundbar or the TV Struggling to process the sound correctly. However i have never had any of the above issues when using headphones or the TV Speakers.

Setup on the TV:

Speakers: Audio System

eARC mode: Auto

Digital Audio Out: PCM

Pass through mode: Auto

I am also posting this on the SONOS help and XBOX help forums.

Hi,

Does the sound only dropout when using the Xbox? Does it dropout when using an app? Also, if you disable the eARC or the pass through does it dropout?

Hi Pentium_Gladio

Still having issues

The sound is really bad when using the xbox on the dolby atmos setting, drops every other couple of seconds.

When the xbox is off and we are watching tv via the DVB tuner or an app on the tv e.g Disney plus then sound will randomly drop out. 

Disabling eArc we get no sound through the soundbar. Changing to auto 1 and auto 2 we also lose sound completely too. 

Posted on the sonos forum too, still no solution.

*****UPDATE ******

So thought id check back in and give an update in case it helps anyone else. 

The issue on the TV still persists, the sound cuts out randomly when watching apps (Disney+, Netflix etc), when watching Live TV and directly through the DVB Tuner. 

Further more the Xbox Series X has sound cutting out every 0.5 seconds when set to bitstream, dolby atmos and 4K@120hz.  I change the xbox back to 4K@60Hz then bitstream & dolby atmos works fine. Another issue being that dolby vision only works at 4K@60Hz due to the TV's restrictions. There is an enhanced setting within the tv HDMI output for dolby vision but both 4K@120hz and dolby vision do not work. 

This has been found out by further experimentation and more people across the internet doing research and putting up videos and articles regarding this TV, soundbars and the xbox series x. 

The conclusion being a poorly configured eARC HDMI. All fixable according to the experts via a firmware update. Which is great but frustrating this has not happened yet on a TV that was advertised specifically as 'Next Gen Gaming Ready'.

I am now in the process with Sony Customer services to sort a fix or return the TV and purchase something that is advertised correctly and works.
