I've purchased a Sony HT-CT800 to connect to my Sony KD55 8500D.

 

I connected today, but sadly there is no TV sound through the soundbar, so posting hoping someone may be able to shed some light as to why?

 

Here's my set up:

 

I have connected via HDMI as follows:

 

- TV: 'HDMI 4/ARC'

 

- Soundbar: 'HDMI Out TV ARC'

 

I successfully completed the set up process for the CT800 via HDMI 4 on the TV - the TV is clearly seeing the soundbar via HDMI 4/ARC.

 

The soundbar is working:

 

- via HDMI/ARC 4 on the TV, I confirmed via the soundbar menu that the sound test worked ok

 

- I Chromecasted audio from my phone.

 

My problem is that when I set the Soundbar input to TV, there is no sound at all.

 

On the TV settings - if I set the speakers setting to: 1 - 'TV', the sound is via the TV speakers. 2 - 'Audio system', there is no sound.

 

I have powered off everything and tried different sequencing for powering back on, but to no avail.

 

I have also tried playing with the Bravia Sync settings on the TV, but to now avail. Bravia sync on the TV can't see any connected devices.

 

So, I'm at ta loose end. This should be very simple - Sony to Sony, 1 HDMI cable!

 

Any suggestions would be welcome, thanks.

Do you have a sound menu somewhere on the tv for digital sound format? Soundbar may not support some of the more advanced sound formats?

No advanced formats, no sound from standard TV

On my x90e ARC is hdmi 3, and I have it connected to one of the side hdmi ports on the sound bar not the one directly behind with the Ethernet port. That’s how mine is setup and working flawlessly

I had this problem or one exceptionally similar with a Samsung TV and a Sony Soundbar. Turned out the cable was the problem.

Thanks for your reply. Yep, when googling I found you previous issue. The HDMI cable I was using was the one Sony provided, so should be ok. I did try swapping out the cable with another, but no difference.

 

But I did have two other devices connected to the TV via HDMI - a WDTV live and DVD. So I removed both of these HDMI cables, leaving only the soundbar via HDMI, and rebooted everything. Hey presto, it worked!

 

Glad to have sorted it, but it should be this finicky!

Were all the other devices powered on? Some will cause problems when powered off and load the CEC pins down so that all connected devices cant communicate. The raspberry pi old version was a well known offender for that.

No, none of the other devices were powered on. I rarely use either, so leave off. Hopefully will not be an ongoing issue.

ARC / CEC is fine if you have a TV and a soundbar OR TV and amplifier.

 

As soon as you start plugging in more HDMI devices you start seeing problems, especially on computers where video cards aren't updated or they've jammed in bare-bone HDMI connectivity. The other big PITA are cheap set top boxes and media players... look out for them.

 

Oh yeah, older devices that run old versions of HDCP (copy protection) are also culprits and cause all sorts of handshake issues.

 

The ultimate solution, get a smart remote control and forget HDMI CEC.

Yep - ARC uses pins that were un-used before HDMI 1.4 - so if it's an old cable it may not have those pins connected - see : https://www.rapalloav.co.nz/blog/HDMI-Audio-Return-Channel-ARC/

Update the firmware and do a factory reset. If ARC is working properly, TV will power on when you power on the soundbar. And vice-versa. If it still misbehaves, call 0800 766969 and tell us how much fun that was.

So the TV (KD-X8500D) and soundbar (HT-CT800) have lost their ARC connection. They were working ok, briefly, until I played a DVD through the soundbar HDMI, after which the TV refused to recognise the soundbar. The TV does recognise there is a device connected to HDMI 4 ARC - I can switch to the soundbar menu OK, it just doesn't recognise it as a soundbar for ARC audio purposes (for the brief time it worked, the HT-CT800 model number was shown against the HDMI 4 on the TV.

 

So if I go to HDMI 4 ARC on the TV, the soundbar UI displays OK - I then select input TV and am instructed to select the TV channel on the remote. I do this and TV channel appears - but when I go to the speakers on Action Menu and change to audio system there is just silence.

 

I have updated firmware and factory reset both the TV and soundbar, but to no avail.

 

The TV only has the one HDMI connection to the soundbar, and the soundbar has a two devices connected via HDMI (WDTV and DVD).

 

I am using the HDMI cable Sony packaged HDMI cable with the soundbar, so assume it should be compatible.

 

I'm about to give up on ARC and buy an optical cable and reluctantly put up with two remotes! Incredibly frustrating to say the least, this is a late model Sony TV and Sony soundbar. I specifically purchased a Sony soundbar so that it would play nice with the TV. So much for that theory!
