I checked them last time you reported this jjjackson. There were no issues then and not now either bud.
Unless I am not testing the same channels that you have, they have sound here.
I have a Dreamlink HD. No sound on movies from Baby Driver through Churchill on my Samsung TV or my HT system in the living room. Everything else seems to work fine. Please check'em out and let me know what you find. If there's a problem, I doubt it's on my end.
Baby Driver - audio check
47 Years Down - audio check
The House - audio check ....very funny, BTW.. and I hate Will Farrow movies !!
StarShip Troopers - audio check
Churchill - audio check
audio working on movies listed above
T1 Plus with HDMI and some obscure TV
No problems on my end. Although I had to leave baby driver part way through and later when I reopened it and fast forwarded to where I left off there was no audio. I will try it again later.
What I'm thinking is that there is some kind of coding that prevents some software from decoding the sound on playback. Some may work and others STB's won't. I think you might need to redo some of the files you bring in.
I've noticed that some stuff I get online allows me to play sound live, but not play sound on a downloaded copy on my mac.
