I didn't realize it was a Roku-TV. If it's completely standalone, then it's something between the service company (not likely), the router, and the Roku-TV. The fact that it can work for days makes me wonder if your router and TV are communicating poorly. If a TV is in another room from the router, the 5GHz can have a hard time getting through some walls. That's the reason you would use the 2.4GHz. Us the 5GHz if it's in the same room because it's astounding how much more information you can receive over a 5 vs 2.4. Also, if it's on a 2.4GHz, then so is the microwave and most old telephone sets. I've gone through this personally where you have too many devices on these bands and then you start working with Channel settings inside the Band. You feel like a communications specialist after a few days of studying all this stuff. Everything from how many wireless computers, printers, smartphones, etc... My Smartphone and television did not like each other. Set all the Smartphones to different channels inside the 2.4GHz and all the computers and printers onto the 5GhZ. Then the Roku in the same room with the router to 5GHz and the other television in the living room on the 2.4GHz. As I said, it took several weeks of reading all this technical stuff before everything worked like a charm.
This is one of the reasons customer support just won't answer the phone anymore. Just who's problem is it . . . everybody and nobodies.
I have two Roku Express and two Roku Ultra. One three Samsung TV and one Samsung Tablet. What are you hooked to? Kind of helps to know what we're dealing with. Kinda helps if you tell us about the router/modem. Further, just how are they configured? Are you on 2.4 or 5GHz? Never had any problems with the ROKU, it's always the configurations.
Hello ssmccloud. What Roku model do you have? We looked at the Roku 3 in my family’s home and the following options were available. - auto detect, PCM-stereo, Dolby Digital, Dolby Digital Plus, Dolby Digital, DTS and Dolby Digital Plus, DTS. Did you try any of the options (besides auto detect)?
I would try Dolby Digital since this is a pretty standard audio compression technology that you’ll find in many radio shows, movies and TV broadcasts. I have a hunch that there might be some kind of issue with the auto detect option and that “forcing” the system to work in a specific format might help.
I have a Roku Express and up until yesterday it worked just fine. Today some films and tv series on both Netflix & Amazon Prime are silent and at least one had voice and no picture. Then there’s the problem with the mouth not being in synch with the voice. This is frustrating. Can someone help? Thank you.
I only have the lack of audio on some films and some series on both Prime and Netflix. I have unplugged the power cord and even deleted Amazon and re-installed it and nothing changed. Now I’m having the synch problem, too. I have a Roku Express.
We have several Roku Express, but one in particular seems to have this problem pretty much daily and has been happening for several months. Interestingly, it does have sound for the menu buttons, but the streaming audio is silent. Changing inputs, HDMI cables, and audio settings have not helped so far. System restart or power cycle is only thing that works (temporarily). The Roku help info on this issue is not that helpful and seems to imply that if the system restart works (even if it is daily or multiple times per day), then all is well. That's a band aid, not a solution.
