KanaaN Mini DisplayPort to HDMI doesn't work on 2013 MBA but does for 2011 Air?

This cable has worked well with my wife's 2011 air for ouputing audio and video through our Onkyo receiver:

However, I can't get it to work on my new 2013 Air. My Air's display will flash like other Air's do when you plug in a cable, or power on a receiver connected by cable to my Mac. But I can't see external speakers in System Prefs/Audio/Output. An no sound outputs.

Both my wife's Air and mine are Thunderbolt so can anyone think of a reason for why this would work on hers and not on my 2013 Haswell air?

Thanks.

All I can say is that this one works on my 2013 11" MBA and 46" Sony LCD TV:

I also tried it once with my 2011 13" MBA and a cheap little Dynex LCD TV and it worked fine.

Ok, sounds like I'll need to visit the Genius bar to investigate.

Does it still work with the 2011 MBA? Going to your Amazon link, the "most helpful critical review" says

I have had this now for 8 months and it seems to have stopped working.

Are you sure the Thunderbolt port is working on your MBA? Do you have any Thunderbolt disks? Or a miniDisplayPort adaptor you can try with a DVI monitor?

Yes, the cable still works perfectly on the 2011 Air for outputting sound.

Unfortunately I don't have any other Thunderbolt/MiniDisplay Port cables or items to test my 2013 Air on.

Update

Unfortunately I don't have any other Thunderbolt/MiniDisplay Port cables or items to test my 2013 Air on.

Update: went to the Apple store and tested my 2013 Air using a Belkin cable and it worked fine. So that rules out my Air as the source of the problem.

Kanaan tested the cable on one of their own 2013 Air's and it worked fine. So they kindly sent me a new cable and that still didn't work on the 2013 Air. But like the old cable is works perfectly on my wife's 2011 Air.

So Kanaan decided to issue me a partial refund, which was nice of them as the old cable was well past warranty. But I really would like to know what the problem is?

I would think if it was a software issue it likely would have also affected the Belkin cable I tested at the Apple store. It would seem incredibly odd if for some reason this cable was only doesn't work on my specific Air, right?
