Newer Technology (http://www.newertech.com) has released the US$59.95 NewerTech Mini DisplayPort with Digital Audio to HDMI Adapter, which integrates the video and digital audio output of Macs without Mini DisplayPort audio support into a single HD 1080p video and full digital audio 5.1 output to HDMI solution.
Featuring a dedicated TOSLINK audio cable that provides the audio signal from a Mac’s headphone jack (or mini jack), the NewerTech Mini DisplayPort with Digital Audio to HDMI Adapter overcomes the non-audio support of 2008-2009 Mini DisplayPort equipped Macs. By providing support for full 5.1 channel digital audio (such as Dolby Digital) along with high definition video up to 1080p, the NewerTech Mini DisplayPort with Digital Audio to HDMI Adapter is designed for using a Mac as part of home theater set-up. It’s bus powered, so no AC adapter is needed.
Owners of the new 2010 MacBook Pro computers as well as in Late 2009 iMac models that feature the latest DisplayPort 1.2 specification that supports audio output can add the $24.99 MSRP Mini DisplayPort to HDMI Adapter and output both high definition video up to 1080p and surround sound digital audio to HDMI interface equipped High Definition televisions with a one cable adapter solution.
