Hi there, 

I have two boxes and used a stereo headset hooked up to the optical on my living room tv. It stopped working. So switched it for my bedroom box and it worked for three weeks and now it stopped working too, just the optical nothing else. Is there a setting that I need to change?

thanks

What are your box's

That's not an answer You  need to post firmware and software version too

My box is a x5 128AL

firm V20230815

5.0.919

does that help?

X5 128AI

Have you checked under Settings->Device Preferences->Display and Sound->Advanced sound settings, and make sure that S/PDIF is still turned on ?   

It can happen sometimes after a s/w update some settings, like S/PDIF and Force Max Volume, will sometimes toggle.  I know it is not ideal, but it does happen sometimes.
