I hadn't realized that folks were linking the Cirrus DSP chips to HDMI input itself. Even without being in the know, that seems unreasonable - the latest 49700 chips (the chip mentioned in Outlaw's October "Double Down" newsletter) would reasonably be equivalent to the 49300 in the Model 950 and the 49400 in the 970 and 990, which obviously had no relation to HDMI at all.
