Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
I have a Roku 3 and so far it's been working great. But I ran into a problem when I plugged my Passport in and tried to play downloads. Some play ok and others have video but no sound. A recent example is I bought the BluRay of Hostiles and downloaded the DVD to my laptop and transferred it to the Passport. The movie plays great when I plug the passport into the laptop and then output directly to the tv with the HDMI. But when playing thru the Roku 3 it has a great HD pix, but no sound. I've tried everything I could think of, but this one's stumped me. Some programs I downloaded play fine on the computer, but not the Roku. Others are fine. Any ideas.
Roku players only support a couple of audio codecs, most commonly used is AAC and AC3. And of course your TV has to support both or you don't get sound. AC3 is no problem, since that's the TV broadcast standard in North America, and probably most of the world. See this page for the exact specifications of supported media. Notice that the container matters as well.
