I think my active able failed

I ran an active hdmi cable from the receiver to the TV @ 2 weeks ago. Better picture. I have a 20ft run. Last night the video feed was fine, but it dropped the audio. Nothing in the set up was changed. The audio sounds like it is cutting in and out making a popping sound and I can't make out any of the sound. Is this a bad cable with the video still working? Thanks., Brian

 

I will reset both cables to see what happens. Cable is a high quality monoprice unit.

 

I am streaming through a Roku device into the Yamaha RX-A780. Using a Samsung TV. Using the Yamaha for sound via ARC.

 

OK. I pulled and reset all the cable ends. No change. Then I switched cables from the Tivo hdmi 2 to the Roku hdmi3/ARC. No change. Switched them back and restarted Roku and the sound returned for streaming via Roku? Restarting the Roku must have fixed the problem. Tivo worked fine. Settings for the Yamaha were not changed. Sound is set on auto for the sound decoder. Sound is more surround sound than it was before for some reason. I only have a center and two bookshelf speakers set up, but it is different. Spoken language in a movie is more difficult to hear unless I turn it up. I am 63 and maybe hearing is starting to go.... Not sure what the problem was.

 

everything is on auto update and is current. thanks.

 

thanks. for my own learning curve I would love to know what was wrong initially. Ghost in the machine. thanks to all.

 

Now for the other shoe to drop. I use a harmony remote for these devices. My watch Roku activity is set up to have my yamaha control the volume. It is set this way in the harmony, but the tv is controlling the sound. I've reset the activity twice on the remote, but ...
