@bryderx Welcome to the forum and the world of Sky streaming. The lip sync issue you are experiencing is a known problem which Sky ave been trying to resolve for a number of month. The advice given by Sky is to change your Audio Settings to PCM or passthrough as a temporary measure whilst they find a permanent solution.
I use a Stream puck (not Glass) but experienced some lip sync issues in the past and I found Dolby Digital Plus seemed a suitable solution (try all the settings in the hope that one will remove the problem). Since getting the QS028 update I have not had any more lip sync problems but am fully aware this has not been the case for many subscribers. I am now on the most recent QS030. 521.00P update and hopefully lip sync issues remain a thing of the past.
