Connecting insignia sound bar to insignia Roku TV using optical cable
I have been using an insignia sound bar with my Roku tv for several years. For the last month or so the sounder stopped working. I have gone through all the steps for setting up and it still doesn't work. The sound bar works with my phone's bluetooth so I know the sound bar works. When I adjust the volume when the tv is on and the sound bar is on, the light on the sound bar will flicker in response, but the sound only come through the tv. I've tried various audio settings and although the sound bar manual states to connect to "PCM" that is not an option. My TV software is totally up to date. Any ideas would be wonderful!
