I can't get the remote to learn to change the volume on my sound bar

I'm having the same problem with a Bel Canto Pre6 preamp--my universal remote has learned the volume up/down from the BelCanto but neither the BelCanto or the Universal register on the apple signal bar at all.

I'm a bit confused. Did you go to Settings > Remotes and Devices > Volume Control? From there you can set IR based audio systems. I don't have your system, but I works great on my Bose sound bar

I have a Samsung sound bar and I am having the exact same problem. It seems to "learn" the IR commands, but then simply does not repeat them back correctly. Hopefully it gets fixed soon.

I cant help, but I have an LG sound bar and it automatically connected, the remote will also turn on/off the TV also, which is an LG, both are 2015 models.

Dose it turn on your soundbar too?

Yes, both the TV and sound bar come on along with the Apple TV. I can control the volume with the remote. I really didn't expect it to just sync up and work, I have always used my harmony controller with the older Apple TV 2 so I'm not sure if the Apple TV 2 synced up or not with the Apple controller, which I never used anyway.

I have a samsung sound bar same problem, how to fix??

I have the exact same problem. "Volume Control - Learn New Device" guide does not register my original remote to control volume via IR on my B&W Panorama reciever. Tried with two other IR remotes (LG and Logitech Harmony) just to verify any signal issues with my B&W remote.

None will register and move the "Progress Bar".

Really hoping for at fix as this would make me retire my Harmony Remote finally.

Same problem with my Pioneer amplifier. The ATV learns the volume up/down buttons, but can't adjust the volume.

Same problem here. I have the Samsung HW-D450. The learning process appears to work (says it does, anyway) but the remote has no effect on the soundbar. I remember that my Panasonic TV remote was not capable of learning the Samsung and I had to use a Harmony to reduce my remotes. Something unique about the Samsung soundbars?

Same problem here too, funny thing is my $9 universal remote from Walmart works fine but my new $79 Siri remote is a no go!

Same problem with a Samsung HW-F550 soundbar. I can get the Siri remote to turn on and off my Samsung TV and the soundbar, but programming the Siri remote with the volume function from the soundbar remote is a no-go. As others are reporting, it goes through the learning process successfully, but then the Siri remote doesn't activate the soundbar volume function. So frustrating, it's a simple IR code and beam.

Same problem with a Phillips Soundbar Home Cinema Speaker CSS2123B. Setup says successful, but the soundbar barely registers button presses on the Siri Remote. Up does work better than down, and if you press the buttons repeatedly, it's kinda sorta usable. I tried learning it from the cable remote, which works soundbar's volume up & down fine (but not power), but, alas, the results were the same. Hoping for a software update fix. There are many IR receivers, soundbars, and systems available throughout the world.
