I seam to have gotten surround sound working



Go to "Applications" then to "Utilities" and open "Audio MIDI Setup"
and click a plus sign "+" in the lower left hand corner to set up
an "Aggregate Device", use the three "Built-In-Line Output" and also
the "Built-In-Digital Output"



then click "Configure Speakers" add a
check buy

"Stream 1 has 2 channels (1-2)"
"Stream 2 has 2 channels (3-4)"
"Stream 4 has 2 channels (5-6)"

but leave "Stream 4 has 2 channels (7-8)" unchecked and click
"Done",



now go to "System Preferences" then to "Sound" then
"Output" and select "Digital Out" and you should be done


I have done that many many times with different drivers, and it never worked
so it must be the new driver, so far I have only tried coax out, but it worked
just fine with a DVD, it shows "Dolby Pro Logic" on the receiver, and I am
getting sound out to all my speakers
