Question about UE Boom 3

I got a second Boom 3, but now the audio is delayed on Windows 10. Not noticeable with Spotify, but everywhere else of course. With Youtube, films and games, the audio is about 1 second too late. I couldn't set up a stereo mode on the Windows PC like on the mobile phone. Does anyone know anything about this? I would like to use the two speakers on the left and right of the PC.
