I had a Sony surround system, when bluetoothing music for music from all speakers I would have an audio setting for "All" speakers to play sound equally. Which filled the house with music and it was really nice at a low volume.
I bought a Samsung surround 5.1 for the wireless rear speakers but now there is no setting for all speakers to be forced to be active. And the remote is awful, designed for a tv or set top box.
Anyway, is there anyway to push left and right channels to all speakers on this Samsung HTS?
if it has the feature, it will be in the surround sound modes options. on pioneer units like mine it is "ext stereo" though might be called all-channel-stereo or other names on different brands. i would cycle through your options.
if it doesnt have it in the menu, you might not have the feature.
