Mini Displayport, USB, and Toslink Audio to HDMI® Female Converting Adapter
Connect your mini DisplayPort and Toslink equipped MacBook®, laptop, or PC to an HDMI® display using this Mini DisplayPort and Toslink to HDMI Adapter.
This adapter converts the mini DisplayPort signal and the Toslink signal from the 3.5mm digital audio output to an HDMI audio/video signal. The adapter supports resolutions up to 1920x1080p, up to 36-bit Deep Color (12-bits per channel), and high-definition, multichannel audio, including DTS-HD Master Audio™ and Dolby TrueHD™. The adapter is powered using an available USB port. Note that this is not bidirectional and therefore will NOT convert HDMI video to mini DisplayPort.

I don't know anything about this, except that it's made to be used with Macbook, which I don't own, and the Toslink audio cable is a fiber optic cable, which is what I use to connect my 7.1 to my Denon amp due to its capabilities and clarity.
I don't think it's ever been used my dad bought it thinking it would work with his iPad (I have no clue why) then gave it to me in case I could use it (which I can't) but I know a lucky Listian can use it! ^_^
