I hope this is the right forum for this. If not, please let me know.
I have an issue that I just discovered once I replaced a piece in my system. I have an optical coming out of my 10 year old plasma TV into a new Elac DDP-2 that I use as a pre-amp and DAC. When I have the Over The Air antenna selected as the output from the TV I get this really fast ticking noise through the Elac optical selection. However, the crazy thing is that I do not get this ticking noise when I have my Amazon Firestick output from the TV into the exact same optical input on the Elac and through the exact same optical cable. So, to clarify, the only thing I change is the "input source" on the TV. Nothing else changes but I only get the sound when watching the local channels over the antenna through the optical. If I just turn the volume up on the TV then that works fine but of course it is not good sound.
The odd thing is that I did not get the ticking when I previously used a Pioneer receiver as the pre-amp. And, just to make sure it was not the Elac causing the issue, I hooked up my Mytek and used it the same way and got the same noise. So, it seams there must be something going on with the plasma tv causing the issue but it was resolved with the Pioneer and so I never noticed it before. I have gone through all of the settings in the tv but did nit see anything that looked like it could be the issue.
Any thoughts? I really want to keep the Elac and also I prefer not to have to add another device in the chain.
