Sony Sony HT-A5000 5.1.2-Channel Soundbar with Dolby Atmos and DTS:X SUB NO LINK Error Fix: Wireless Subwoofer Not Connected

Error code SUB NO LINK on the Sony Sony HT-A5000 5.1.2-Channel Soundbar with Dolby Atmos and DTS:X means: Wireless Subwoofer Not Connected. The wireless subwoofer is not producing bass, or the LINK indicator LED on the back of the subwoofer is blinking (indicating it is searching for the soundbar and has not connected). The subwoofer must be paired with the soundbar wirelessly. Place the subwoofer within 3 feet of the soundbar for the pairing process. Press and hold the LINK button on the back of the subwoofer for approximately 5 seconds until the LED flashes rapidly, indicating pairing mode. Within 60 seconds, press and hold the LINK button on the back of the soundbar as well. When pairing is successful, the subwoofer LINK LED will stop blinking and remain solid green. If pairing repeatedly fails, unplug both the soundbar and subwoofer for 60 seconds and try again. Wireless interference from a Wi-Fi router operating on 5 GHz can disrupt the wireless link — try repositioning the subwoofer away from the router.
