Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

The cable for the HDMI connection is probably cheap, and one wire is defective.

Unless it is of the best quality (and fairly pricey) HDMI cables are prone to this sort of defect.

However, try several things:

- re-seat the cable at both ends with both devices turned Off.

- consider the cable's quality.

- and, the most complex thing to do: Check all settings for Sound (Sound Options in the TV's Menus for instance, need to be correct.)

Let me know what happens, and what you find out by this means.

Hi, thanks for your reply.
Turning devices off and back on every time seems to work, however, I wish there was a permanent solution.

If you are turning the devices On, in the first place and before the error has happened, in a particular order (i.e. one before the other, or simultaneously with a switch common to the power to both, perhaps), then try turning them On in the other order, I suggest. Initializing of the HDMI connection may require it, if there is nothing else wrong.

And it is something to try.
