Just bought on of these soundbars for £80 to go with my fz802. Plugged it in and lip sync issues. Plugged it into hdmi2 so I can control it via arc. I haven't tried bluetooth or another HDMI as I wanted to use it via arc.
I had one but the lip sinc issue was there but bearable. The advice I got was to try to reduce all the artificial picture processing thats going on within the tv via the picture setup menus, that ultimately was causing a delay with the pic or the sound, couldnt work out which came first.
