Does not recognise HDMI connection after a while

[daniel_K]

I really don't like to hear that. Is there a way to check the firmware version to see if it changed on the Dione?
Is there any workaround, like manually re-pairing HDMI ARC? Or how are you handling it now? Thanks for the response.

Yes - in the app. And NO - THERE IS NOT any firmware upgrade for 2.5 years.
Everybody is waiting.
Much more likely your TV got an upgrade and make thing behave differently.<

EDIT: Feel free to check

Last update Dione 2.16.1 more than 2 year ago.

Hello everyone,

We have now also bought a Dione and had the same problem with the HDMI port from day 1. We have a Sony AG9. I have to reset the soundbar every time because at some point in the middle of a movie it loses the connection and there is no more sound and it can no longer be controlled. Over the Christmas period, I used the temporary solution via the optical audio connection. This is an unpleasant option because you have to control everything via the app. Of course, everything is easier to operate via HDMI... I just don't understand why there hasn't been an update for so long. My answer from Devialet Support on 23.12.2024: Hello Daniel,

Thank you for your feedback.

This phenomenon occurs with some TV models. We have already solved this problem for several of them, and those still affected are being dealt with as we go along. We apologise for the inconvenience!
These televisions don't check when they're switched on whether an HDMI soundbar is connected, they wait for a signal from the soundbar to tell them so. Except that the Dione only transmits this information at start-up.
In practical terms, if the soundbar has not been switched off and you switch on your television, it will not look for a signal and will not receive one from the Dione because the latter will not restart. The application will give you the error message ‘No cable connected’ and no sound will come out of your Dione.
For the moment, the solution is to turn off the TV and the Dione and then turn on the TV first and then the Dione.

An update is planned but no date has been announced for the moment. Otherwise, we recommend that you temporarily use the Dione in optical mode.

Have a good day.

Very unfortunate with the software, also the fact that volume 35 is always selected after a restart is very annoying...

I would be really interested to know if there is any Sony TV owner who has got the Dione running via HDMI without any problems...

Best regards
Daniel

PS: Our Dione gets extremely hot on the underside - is this also the case with your Dione?
