I'm using Roku Premiere (Model 3920X) and have lost audio...it's been working fine since I purchased less than a year ago. The Roku device is connected directly to the TV using HDMI. I tried using another HDMI cable, no luck. I tried changing the audio settings (Auto vs. Stereo) and still no luck. I hooked my laptop to the TV using the same HDMI cable to ensure the TV speakers are working and they are - so that's not the issue. The channels/networks I watch that are impacted by no audio are Hulu, Netflix and YouTube. Any help would be greatly appreciated.
