OSX Mavericks system wide Stereo upmixing

I have been trying to figure out take the 2 channel output from my mac running mavericks. - iTunes - Safari - Quicktime - Etc.

And upmix to use all the speakers in my 5.1 surround sound.

MIDI Setup

I would like the left channel from the stereo mix to play on Left Front and Left surround and the right channel should play on right front and right surround.

I have tried Jack Pilot and SoundFlower both of mix do not seem to work correctly on mavericks.

If anyones has any ideas that would be great!

How are you connecting the mac to the speakers/amp? What interface are you using? – Tim – 2014-09-08T03:52:10.670

I am using a USB external sound card. The speakers are connected to it over 3.5mm cables – Zen_Silence – 2014-09-14T15:39:54.087

What if you choose channel 1 under both left front and left surround, and channel 2 under both right front and right surround?

Edit: The above does not work. Maybe I found a solution but I cannot test yet since my 8-channel DAC did not yet arrive.

Solution: install Apple's AU Lab and add a new configuration (it's the "+" button at the bottom) under user configuration, where you can define input and output channels. You have a matrix mixer to route channels as you wish.

Its been a long time since I had this issue I eventually solved it using a 3.5mm jack splitter very hacky solution.

I think I did get it working with the AU Lab but I think my problem was I would always need to have AU Lab open to get it to work. – Zen_Silence – 2015-02-03T00:47:43.490
