After years of using a wired Bose sound system, I just got a Soundlink Color II for use with my computers. I'm currently using it with my Mac desktop, running the latest version of OS-X. The firmware on the speaker was updated during the initial use. The problem I'm having is that the audio is out of sync with the video, the audio lagging slightly behind. This is my first Bose Bluetooth speaker, so I don't know... is this something I'm going to have to live with or is there a fix. It's quite annoying.
