remote IR issue

New installation. AMP connected to LG TV with Xfinity cable service / remote. AMP wirelessly powers two ONE SL speakers. AMP connected to LG ARC output. Volume can be heard in the speakers. Remote will now control speaker volume. Remote is recognized by the AMP as + / - volume indicator is visible on screen.

What step did I mess up during installation to compromise the IR Remote control ONE speaker volume? Any suggestions to resolve?

Hi pgaynor002

Your post at first read does not make sense, There is no way that a Sonos Amp can power one or even two Sono One SL speakers. The Sonos Amp is designed to power 3rd party speakers that are wired to it.

You can Group Sonos One SL or any Sonos speaker to the Sonos Amp to allow them to play whatever audio is being sent to the Sonos Amp.

Your Sonos Amp may very well be connected to your LG TV via the HDMI_Arc connection. Grouping the Sonos One SL’s to the Sonos Amp will send TV Audio to those speakers. In the Sonos App you can control volume as a unit or individually by speaker/Sonos Amp.

In any scenario just because the audio being sent to the Sonos Amp does not mean it is powering other Sonos speakers that are grouped to it playing the same audio.

BTW...most likely you are hearing a audio delay for TV audio sent to the Sonos One SL speakers.

Using a remote to control volume of the Amp will not change the volume of any speaker Grouped to it.

Could it be that the Sonos One SL’s are being used as surrounds BONDED to the Sonos Amp? Please clarify how the Sonos One SL’s are being used.
Good analysis by @AjTrek1. Could you confirm that you have passive speakers playing the role of front speakers, wired to the Amp?
