I have an LG Oled Smart TV and a Vizio soundbar and everything worked fine until I moved from DISH to Spectrum. The soundbar is connected via HDMI Arc. When using the non volume buttons (FF/RW, up/down, left/right, etc.) on the Spectrum Guide remote the sound either goes way up or way down. It appears to be some type of conflict with the soundbar. If I unplug the soundbar and use the TV speakers everything works fine. Even Spectrum Technicians say this should not be happening. When streaming videos (not using the Spectrum HD DVR box) I use the TV remote to control the volume from the soundbar. without any problems. Any suggestions?
