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

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 SONY help and XBOX help forums.

Does your TV have the latest firmware installed? Try unplugging the TV and Arc from power for about a minute. Also try setting Digital Audio Out to Auto 1 or Auto 2, not PCM.

Hi GuitarSuperstar

I can confirm the software is up to date, ive just ran the update software function again to make sure.

Kernel Version 4.9.125 #1 Wed Feb 3 2021

Ive tried all settings, on the Digital Audio Out too and some even lose the sound completely.

Just unplugged everything too and hasn't fixed it.

Is that the Sony firmware v6.0466? (24th Feb)

Hi Ken_griffiths

 

Software version: PKG6.0466.0059EUA

 

So yes it looks like the firmware you suggested.

 

 

In that case, if you perhaps ‘temporarily’ disconnect your other hdmi connected TV peripherals, see if that stops the dropout issue. If it does, then that may suggest one of your connected devices are using HDMI-CEC too and perhaps stealing the focus away from the Arc.
 

You can try discovering which device is responsible by adding each device back to the TV, one by one… if you can go onto discover the device and are able/okay with switching off it’s HDMI-CEC feature then I would do that and all being well the issue will go away. 
 

Note some devices do not allow the switching off their HDMI-CEC control in which case you could use a CEC-Less adapter instead, like the one shown in this link:

Hi Ken_Griffiths

 

Still having issues and extremely disappointed this is happening with a £800 soundbar.

 

There are only 2 devices connected the xbox and the sonos arc. The xbox is off whenever we have issues with sound dropping when watching purely tv and using the tv apps.

 

Is there a chance the soundbar could be going into a sleep mode for a couple seconds 10-20 seco after a set time period?

kinger251285,

Did you try disconnecting the other devices, just temporarily as mentioned, and did that solve the matter for you? Just trying to establish if the HDMI-CEC protocol is at the centre of your issue? You are best to uncable the products whilst testing.
