I've tried about 20 5 digit remote codes on the universal remote, all supposed to work with Samsung soundbars. Several of them even get the remote to blink twice, suggesting that it is the right code, but so far, none actually work.
It's frustrating because you know there is a code that will work.....just don't know what it is!
If your remote doesn't have the correct IR codes preprogrammed in you can't add them. The number you enter to access the codes is just where the codes are stored not the actual codes.
If you get a Logitech Harmony remote it is programmed from their huge online database. If the codes for your soundbar aren't there you are instructed to teach them into their database so the next user will find them. That's how they expand the database. The remote operates your entire system and has macros. Well worth the price.
I've tried the logitech harmony 350. I find that it switches on the soundbar and cable box perfectly except that about half the time it doesn't turn on the Sony tv. There is a clear line of sight to the tv and I'm pointing right at it. Even raised the tv about 3" to raise it above the soundbar. Has anyone else had this trouble with the harmony not turning on some devices? I never had the problem with the Comcast remote. I wonder if a Phillips universal remote might do better....
