New tv w Vizio sound bar connected via optical cord. Trying to watch a football game on espn, through Xfinity cable, and the vocals of the announcers seemed buried in the mix with the ambient stadium/crowd sounds overwhelming the announcers audio. I tried different settings and settled on stereo. Didn’t seem to matter. Bought today. I found another thread dating back a couple of years that the moderators shut down. I didn’t find any answers there. Suggestions? I bought today so I do not know anything about what operating system is on it and if that makes a difference. The picture is stunning. But if I can’t get the sound right I have to trade it in.
