Wait. If I understand this correctly, if you use the same HDMI port for audio *and* video, they should be governed by the same clock (since, AFAIK, in HDMI audio is transferred during the blanking interval between two frames). If that's the case, why is clock deviation still an issue? Shouldn't they be perfectly in sync since it's the *same* clock? Or are we only discussing the case where audio is transported separately (e.g. analog)?
