Sony Sony HT-A5000 5.1.2-Channel Soundbar with Dolby Atmos and DTS:X REAR SYNC FAIL Error Fix: Rear Speaker Pairing Issue

Optional wireless rear surround speakers (Sony SA-RS3S or SA-RS5) will not pair with the soundbar, lose connection frequently, or produce no audio despite appearing paired. The HT-A7000 and HT-A5000 support optional wireless rear speakers to create a full surround sound setup. For initial pairing, place the rear speakers within 3 feet of the soundbar. Power cycle all speakers and the soundbar by unplugging each for 30 seconds. Check that the rear speaker firmware is up to date via the Sony Sound Connect app on your smartphone. Wireless interference from Wi-Fi routers, microwave ovens, baby monitors, or other 5 GHz wireless devices can disrupt the wireless link between the soundbar and rear speakers. Ensure the rear speakers are powered on and their indicator LEDs show the correct status. Re-pair the speakers following the procedure in the user manual — typically by pressing and holding the LINK button on each rear speaker and then on the soundbar.
