Been unable to figure out how to fast forward or rewind DVR content (or anything else). Thanks for any help. Cable provider is Spectrum. DVR is Arris DCX3510-M

Karan, thank you for your response. I tried your solution, but for some reason, it didn't work for me. I removed the optical cable and connected the HDMI cable to the TV's HDMI (ARC) port and the soundbar's ARC port. Also, via the SOUND settings menu, I set the Sound Out to HDMI (ARC). According to the settings display, this also automatically turned on the LG Simpliink. Unfortunately, something is amiss because I could get no sound from the sound bar.The volume buttons on the magic remote now controlled the the soundbar volume indicator (which was not the case before the connection change), but no sound was produced. Any further suggestions?

I have an lg 65sm9000 . It is attached to a S5430W Vizio soundbar via the optical cable. Although the sound bar operates with my TV, I'm unable to control it with the LG magic remote. I cannot power it on or off and I .cannot control the volume with the magic remote. I have to use the vizio sound bar remote. Does anyone know a way to remedy this difficulty?
