XR-42A90K OLED TV & HT-S2000 Soundbar HDMI eARC issues

[TomDDS]

Just got a new XR-42A90K OLED TV and I'm having a lot of issues using HDMI eARC to connect my Sony HT-S2000 Soundbar. It is so bad I've had to resort to using an optical connection which works fine. Only issue with optical is it doesn't work with the newer audio formats (Atmos) and I can't control volume via the TV remote.

I've tried all the settings on the TV and different HDMI cables including a new Amazon Basics 48Gbps High-Speed, 8K@60Hz, 4K@120Hz but nothing helps.

The issues are as follows:

- If using Dolby Atmos audio either from the inbuilt apps (Amzon Prime, Disney etc...) or on my PS5 the sound cuts out every few seconds. Switching to normal Dolby audio output or DTS resolves it at least on the PS5, no clue how to downgrade the audio on the apps.

- After the TV has been on for a while, especially after being in standby, the connection suddenly stops with the TV showing a connection error, and it reverts to TV sound. The only way to restore the audio out to the soundbar is to restart the TV via the system menu.

I've updated the firmware to the latest June release and the soundbar worked fine on my previous TV via eARC, also a Sony.

@TomDDS 

Is your new HDMI cable ‘with Ethernet’?

Have you tried the HDMI cable that worked previously with your earlier eARC device?

[TomDDS]

I've tried a few HDMI cables, latest one was Amazon Basics 48Gbps High-Speed, 8K@60Hz, 4K@120Hz which is described as Ethernet Ready

Hey @TomDDS 

I can see that there is a new software release for your TV, you can find it here

I also recommend that you make sure that the eARC mode is enabled, by setting it to Auto in the sound settings to be able to receive high quality audio properly, enable eARC mode

And let us know how will it go with you.

[TomDDS]

Ah thats good to know, I'll update it later and reply on how it goes. Hopefully it helps.

I have already tried all the sound settings but will make sure it is Auto when I retest.

Thanks

Initial results are promising. Watched a few Disney+ shows with full Dolby Atmos and it didn't drop out once. Also I've not had a single connection error since upgrading which was the biggest issue. Fingers crossed it is now sorted.

Unfortunatley the dreaded sound drop out started happening again followed by the eventual connection error. This was after playing on my PS5 for a few hours. Got a feeling this is some kind of memory leak as it does seem to go away once I reboot the TV, only to come back after the TV has been on a while.

Anyway back to ever reliable optical cable till the next firmware comes out.

Also does anybody know how I can raise this with Sony. I've tried their support page but all it does is point me to book in a repair which I don't think is the issue here. All I want to do is send them a message of the issues I'm facing...
