Samsung TV & Audio HW-Q990C 11.1.4 Channel 546 Watt Soundbar with Dolby Atmos, DTS:X, and Wireless Subwoofer REAR CHANNEL SWAP Error Fix: Left and Right Rear Speakers Playing Wrong Channels

Error code REAR CHANNEL SWAP on the Samsung TV & Audio HW-Q990C 11.1.4 Channel 546 Watt Soundbar with Dolby Atmos, DTS:X, and Wireless Subwoofer means: Left and Right Rear Speakers Playing Wrong Channels. After re-pairing or moving the rear speakers, the left and right channels may be swapped — surround effects come from the wrong side. During setup or re-pairing, the soundbar assigns left/right based on pairing order or MAC address, not physical position. Fixes: (1) physically swap the two rear speakers (move left to right position and vice versa), (2) use SmartThings app → Soundbar settings → Speaker Test to verify correct channel assignment — the test plays a tone from each speaker individually, (3) factory reset and re-pair all speakers. Mark rear speakers with "L" and "R" stickers after confirming correct placement. The SWA-9500S speakers are identical hardware — left/right is assigned by the soundbar.
