My magnifi mini doesn't emits any sound since i connected it to the internet

When i tried to configure the built-in Chromecast i have to conect the soundbar to the wifi, it connected succsesfully, then a red light starts to blink (a firmware update i guess) the soundbar starts again and then it no longer has any sound, absolutely not one. I've factory reset the bar like 3 times and still have the same issue whit the sound. Any help? Thx
