I pair my HW-N650 with SWA-8500s before this day it work perfect. But this day I have a problem with it. My SWA-8500s output Left and Left Surround channel in same left speaker and Right and Right Surround channel in same right speaker too. How to fix this problem I try factory reset my HW-650 but still have problem.
Can you provide more details of this concern? I just want to make sure I understand correctly. You are getting the audio from the left surround speaker and in the left sub-woofer, is that correct?
My Left Speaker SWA-8500s output sound from Left sound channel and Left surround sound channel
and My Right Speaker SWA-8500s output sound from Right sound channel and Right surround sound Channel.
It should output Left surround sound channel and Right sound channel not two sound channel in one speaker.
I test with this video https://www.youtube.com/watch?v=PqVCPE8_ntE&t=1s and my subwoofer no sound in this test.
Before this day all sound output correctly.
Thank you for providing more details to me. The first thing I would recommend is simply trying to power resetting the device by holding the Sound Mode button for about 5 seconds. If that doesn't help, try toggle between the Sound Modes. Cycle through Standard, Game, and to the Surround mode and see if that helps.
