AUDIO loss

Hi, I have. Sonos Arc with Sonos One surrounds connected to a LG OLED C2 TV. I get loss of audio intermittently when fast forwarding through adverts on recorded TV programmes and movies. When I switch off HDMI-CEC or eARC the sound returns.

Anybody else having this issue, and have you got a solution?

@Ken_Griffiths - I haven’t enabled any gaming settings, but thanks anyway for your suggestion.

 

The latest news is that we have not had any further audio drop outs. I’m leaning towards the HDMI cable being the source of the problem. I swapped a 1m one for a 1.5m one, because the shorter one may have been under a little bit of tension.

Hi ratty,

CEC less adapter has been ordered. Hopefully it will solve the problem.

Hi,

CEC Less adapter now installed, so let’s see if that solves the problem.

    Hi Corry,

    Just lost audio after stopping a NOW TV stream on my BT TV box.

     

    Diagnostics report - 1089833586.

     

    Looks like the CEC Less adapter did not work.

    Hi Corry,

    Just tried to post an update, but it has gone to the moderators. 
     

    Lost audio again, so adapter has not worked.

    Yesterday I did a factory reset on my TV and then reinstalled all my devices, starting with my ARC. I left eARC disabled when connecting the BTTV box (previously it was enabled, but the LG TV software would not allow the setting to be switched off).

     

    Let’s see if this works!

    Hi @RussJK 

    It’s not beyond the realms of possibility - fingers crossed!

    I still see the same errors. It seems something was making the module for decoding the audio crash. How do other sources behave? If you use a built-in TV app or channel, does it behave the same way? Please check the Humax device for any software updates.

    If resetting the TV did not help, to negate any other possible influence other than the feed itself, I recommend you connect the Arc to the TV via the optical adaptor supplied. If the issues continue, then the source of the issue is likely the TV box. This may be able to be confirmed by finding the same issue when using the TV’s speakers.

    HI Corry,

     

    It has happened whilst using the Disney+ app on the TV, so multiple sources.

     

    As a precaution I also changed the HDMI cable linking the ARC to the TV.

    Maybe see what happens when you connect the Arc to the TV via its Optical port, using the supplied Sonos adapter, to perhaps see if it might be the TV’s HDMI-ARC port at fault here.

    @RussJK,

    Also have you perhaps enabled ‘Instant Game Response’ on the LG TV’s HDMI-2 port, if so, then see if switching that feature ‘off’ in the TV’s Picture Settings might help with your issue as it can (in some cases) cause some issues with devices connected to the HDMI-ARC port.
