@rbej and @popcornmix, I'm using the above image and am noticing 1-2 seconds worth of delay on the audio. For instance, start any 'TED talks' session and you will notice the audio delay (notice sound compared to mouth movement).

Is this a known issue ? Are there any adjustment parameters available to the user ?

Not a known issue, although I did see live TV slightly off (300ms), so that may be the same problem.
Do you know the last build that was okay?

You can bring up OSD/audio and adjust the audio delay to fix it.
