I have a projector and connected to it is an HDMI 5 port switch. I have 5 devices plugged in as inputs. I also have an optical cord plugged in to output the audio of the device that’s selected on the switch. This optical runs to my roku soundbar. Works perfectly. Now I just need to program this xfinity XR-15 to manipulate the volume levels. Anyone know of any code I can use? I can’t find a manual code search for this remote either Model:
The streambar uses the same Roku IR code that roku have used for over ten years. With 4 new commands added for tv power, volume up & down, and mute. These new commands aren't roku soundbar or streambar exclusive, they work on all roku that accept IR commands. When any roku sees these commands it initiates hdmi-cec signal over the hdmi cable to control the tv its connected to. Only certain UEI made universal remotes will give you access to these commands by using advanced codes which are 5 digit codes for individual functions. Like the Inteset 422-3 or OFA urc-7880. If you can find a Onn Roku Soundbar remote which is iR only, you could use it to teach universal remote commands. You won't find it preprogrammed into ANY universal remote.
Hdmi-arc and hdmi-cec are two different things, arc sends audio back through the hdmi cable where hdmi-cec sends commands. A tv without arc can still have cec feature, it doesn't use specially marked hdmi input like arc does, just any hdmi. You're using hdmi to send audio & video from the apps on the streambar to the tv right? Instead of using arc to send the audio from the tv to streambar you're using optical.
No I am not using any HDMI connection. I am only using optical and power connections on the soundbar. The soundbar is just playing the audio from the optical connection. I can adjust the volume only with roku remote but was hoping to use the xr15.
