I got the S60T along with a Q80 TV yesterday. Set up went fine, and I had the soundbar linked to the TV via Bluetooth, and I also used the soundbar without the TV to play music through Alexa and Spotify, no problem.
Today though, there's no audio. I've checked that the Bluetooth connect with the TV is set up, I've unpaired and re-paired it, and I switched from a Bluetooth connection to HDMI, but there's no sound. The TV sound setting say the soundbar is connected and selected as the output, I've checked volume levels, and I've checked setup in the smart things app, everything looks ok. The LEDs etc are working on the soundbar, but theres no audio feedback, either from the device itself or when using Alexa. If I try Alexa now, the lights on the soundbar activate like it's listening, but that's it, no audio.
I initialised my S60 after it stopped audio output following a power cut.
With the power on, press and hold the + & - buttons for 5 seconds. The lights will flash. This fixed my issue
