The soundbar I have worked with the tip above when I hit 992 and channel up until it turned off, but my xfinity remote still doesn’t control the volume. Any further tips?
Did you try this?
I just went through this with my Dad. Sceptre uses Sony codes. For my Dad's TV and sound bar, we found 3 -4 different Sony codes for each unit, tried them all until it worked.
Hope this helps.
Many codes enable remote to control vol up/down but none of the codes shuts the soundbar on/off. The tech who visited said it can take a while for new codes to be found and released. That stinks. Also, although my TV is only one year old and has ARC, I was not able to hook it up using ARC. Trying resulted in no sound at all and, yes, I changed all of the TV settings to enable ARC. The ARC set up is not simply plug in an HDMI. It was tedious trial and error and in the end I could not use it. Now using just the optical. Sound is fine but I understand ARC might have been better.
