kdl-50w805c no longer switching hdmi automaticaly

[bridavis]

Hi, I have a Sony KDL-50W805C connected to a STR-DH800 by way of HDMI 1.4 leads. I have recently lost the automatic switching between the TV speakers & the AV amp speakers, I have to now go into the "Action Menu" select sound & then I have to select either TV speakers or AV amp speakers. I have a Firestick plugged into number 2 HDMI on the TV, I was able to select TV on the amp to obtain surround sound from the fire stick which would automatically mute the TV speakers and output the sound through the amp, this no longer works  and I am unable to get sound from the firestick in this configuration. My blue ray player used to automatically turn on & mute the TV but this no longer happens. Any ideas would be great. I have already tried a factory reset on the TV, I don't think the amp firmware is upgradeable.

Hi Bridavis,

Is the amp connected to the ARC port?

In the settings of the TV, is the speaker settings set to audio system?

Hi, 

Thank you for your reply.

All my connections are as you have described as they have always been. I have just figured out the culprit & the reason for my loss of control. I bought a Humax FVP 4000t to replace my Virgin Media box and ever since then I had lost control but after reading of similar instances on the internet I bought a Lindy HDMI CEC Less adapter which I connected to the HDMI port of the Humax & that cured the problem. I don't know what the Humax does to your CEC system but the Lindy adapter cured it.

So thank you to everyone who has got in touch to help me with this issue, problem solved.

Best Regards

Brian.
