Hdmi Arc problems

Hello , I have just got my LG tv and trying to connect my Soundbar to it using Hdmi Arc so I can control the power off/on and volume using the tv remote. I can connect the Soundbar and it will work but sometimes it won’t power off the speaker when I switch off the tv or it switches off the Soundbar but won’t switch it back on , if I then manually switch on the Soundbar there is no sound. I have tried various power cycles and factory resets , tried setting things in different order but to no avail. I have everything set to PCM and Simplink is On. Sound output is set to Hdmi Arc.  I have tried the Soundbar on my other tv which is a Samsung and that works fine. Any ideas?

    slattster, I would recommend setting up the sound bar in the Device Connector also as sometimes the SIMPLINK (HDMI-CEC) may not always communicate properly every time between the TV and the connected device. What is the model number to your TV and sound bar?

    Hello Jamal , isn’t device connector just for use with magic remote ? The tv is 43um7400plb , the Soundbar is Qacoustics M2 . I have progressed with the problem , hopefully you will have a solution to this , I have isolated it down to a Hdmi switch. I have the Soundbar connected directly to the Hdmi Arc input , I then have all my other devices ...ps3,dvd player etc going into the Hdmi switch which then goes to Hdmi 3 , I have tried Hdmi 1 also but get the same problem. If I connect my devices direct without the switch it works ok . How to I get my Soundbar to work while my switch is connected ?

    Hello Jamal , it looks like I have sorted it , I had to disable CEC on all devices connected to the Hdmi switch , all but one already had it disabled , I had to enable CEC on the ones that had a sub menu , disable all the sub menu items then disable CEC again , since doing this the speaker works and powers on and off when the tv does. Hope this helps someone.
