A:AnswerI don't know if you can find a sound bar that small but this sound bar is smaller than the regular soundbars and it doesn't come with the side speaker. It is smaller and that is what I needed in my son's room and it works great.
A:AnswerI'm not familiar with the FireTV setup, but my Samsung has audio settings in the Menu section allowing the user to set up external audio and disable the TV audio. I'm not getting any latency with it. Perhaps you can look there?
A:AnswerI would look on amazon with the model you may find it there or maybe ebay. Just put in model number and it will show you the different remotes. It does come with one.
A:AnswerI would recommend that you attempt to disconnect the soundbar and then try the CBS app.
If it does not occur, check your settings on your TV.
Good Luck!
A:AnswerI have turned the volume down all the way on the TV and use the control on the soundbar. The seems to work the most effectively. Hope this helps.
