I’m also experiencing No Sound problems with my Roku. I don t remember exactly when it started, but it was a few months ago. But the problem has gotten worse. Before, I could just unplug and plug the TV and the sound would start working again. But now I have spent the past 4 days trying to make the sound work again on my LG tv, which has the Roku device and nothing happens. I have tried ALL the tricks and tips, but nothing seems to work and I’m fed up. I will throw this Roku to the garbage. It is a waste of my time and is a pain.
Every time I start up my ROKU TV there is no sound. Going through the setting menus to "reset audio to default settings" by tapping the pause/go button 3 times does the trick Every Time. The problem is that I have to do this Every Time. Is there a way to make the settings stick?
FYI. I responded about this subject a bit ago and I have three different ROKU's on three different TV's. Some of these fixes worked for a few days but the problem persists. If I change for instance from HULU to YOUTUBE on any of the three now, I generally have to restart the ROKU. This has been going on for some time and is becoming annoying to say the least. Come on ROKU, you have a problem. Lets fix it!
I contacted TCL who made my TV. Despite it being out of warranty, I got timely responses to my queries. Mostly, their suggestions were either the obvious, or the ones I have seen here. The last message I got had the procedure below, which may help some who have sound issues. BTW, without doing anything further than the repeated "Press the Play/Pause button three times" trick, the problem has magically gone away. I'm not going to try the procedure below unless the problem recurs.
5. Complete powercycle. (This is to drain excess energy of your TV). a. Power off the TV by using the TCL Roku remote or by pressing the power button on the TV b. Unplug it from the wall outlet c. Press and hold the power button on the TV for 15 seconds d. Power on the TV 6. Perform a system restart. a. Select Settings. b. Select System. c. Select Power. d. Select System restart.
