Does this Mini DisplayPort to HDMI connector output audio? I'm trying to find a relatively cheap Mini DisplayPort to HDMI cable that also supports sending audio to an HDTV. Cables from Monoprice are out of the question, since they don't ship to Romania and I'd rather not spend $40 for a cable sold by an Apple authorized reseller.

I've found several cables on eBay1 that say they support "DTS/DTS-HD, Dolby Digital / Dolby TrueHD, and Linear PCM (LPCM)". All those acronyms leave me completely clueless; they all have something to do with audio, but none of them clearly state "yes, we have audio support". Would such a cable allow me to output both video and audio to a mid-2010 MacBook Pro? Has anyone actually purchased such a cable and had any problems with it?

1. I haven't linked to any of the cables I've found on eBay since I'm not here to drive traffic to their products. Also, I'm trying not to spam this site.

I've bought a cheap one from Belkin for my MacBook Air - but there is no Audio-Output!
