I have a 2.4Ghz Mac mini, which is connected via hdmi through my Arcam avr400.  I cannot get it to play 5.1 surround sound, I have tried toslink, updated my software, but still it won't work.  The avr appears in midi player, and I can test all speakers fine, but cannot play 5.1 through iTunes, any help please?

    Go to Applications->Utilities->Audio MIDI setup.  In the

    dialog box, select your output.  Then set the drop down menu

    to 2ch-24 bit and 48kHz sample rate.   What will then happen,

    when you play back a video in iTunes with 5.1 Dolby, the encoded

    Dolby track will then be passed through the the output and can

    then be decoded by the device.

     

    This is how I have my 2010 Mini setup connected to my Yamaha Rx

    via HDMI and it happily passes Dolby and DTS quite happily to my Rx

    from any app (personally use XBMC as my media app for movies as

    iTunes had just too many problems with video quality).  Dolby's

    True HD and DTS-HD/Master Audio do not work however since

    the video chip in the 2010 Mini does not have the required "protected"

    audio path.

    Thanks Woodmeister50 but I have tried that, I understand that mac minis after 2009 should run 5.1, I am frustrated at how difficult it is proving to sort this.  The Mac mini shows my system though some of the features are greyed out.  I may take it to apple for them to sort, they have been quick to let me purchase software / hardware to sort this, so they can sort it for me.

    Just a thought, are you able to play music through all your speakers?
