Set the DTV box to output stereo PCM audio. Component, of course should fix however that's usually stereo as well.
One morning I turned on my TV (Samsung 4k Smart TV UN65HU8550) and Directv DVR (HR44 Genie) and though the picture came on, there was no sound... On any channel. I've had this set up (simple HDMI connection) for about six months since I bought the TV without issue. This came out of nowhere.
Both of my other inputs (Playstation 3 and Apple TV... Both HDMI) worked fine. So, I switched the HDMI cables in the back of the Genie and Apple TV. Different cables, different ports, same result... Sound on the Apple TV, none on Directv. A hard reset of the Directv box didn't do it either.
I figured it had to be the Directv box. I scheduled a maintenance visit (they were out the next day). We walked through all the checks I had done and, in addition, he reset my SWiM box. No joy. Finally, we decided it had to be the Directv box and I bit the bullet (said goodbye to all my recordings!) and agreed to activate a new Directv box.
But after it started up... Same result! No sound! We took my old box up to the master and hooked up to the tv there (Samsung UN50H6350). What do you know... crystal clear sound.
So, it's not the Directv box, it's my 6-month-old, $3,000 tv! I seem to recall putting through a software update the day before the issue started (current firmware is 1101). That's the only thing I can think of that could have caused it. Of course, Samsung tech support tells me there is no way to revert to older firmware. And that, basically, there's nothing they can do.
I'm currently waiting on delivery of a 12' component cable that I will, after taking this big, honking tv off the wall, run through the plaster&lathe just to get my sound back. And anxiously awaiting the next Samsung software update hoping it will fix the issue and give me back use of my HDMI cable.
Has anyone else seen this? Help!
