Q: Help with 7.1 Surround Sound on iMac (2011)
Hi there, I recently purchased a 7.1 surround sound system to work with my iMac (2011 model). The speakers and everything else are set up fine, and I have the minitoslink to toslink cable connected to the headphone jack in the back of my iMac and the Digital Out going into the reciever, however, I am only hearing stereo sounds.
I've looked everywhere and it seems like the setup I have should be working. When I go into the Audio-MIDI set up I see the "Built-in Output" is selected tosend the audio signal out with the "Digital Out" source. Here's a screenshot:
When I go into "configure speakers..." it has the 7.1 surround options greyed out like this:
What am I doing wrong? What am I missing?
Thank you,

Is there any way to just push the sound through all the speakers (regardless of whether it's true surround sound or not)?
That's a capability if your receiver has it to branch electronically.
You can opt to manually "branch" the outputs of the LF to match the LR and the RF to match the RR, the lower frequencies should be going to the sub-woofer anyway and it doesn't matter where that's placed.
All depend if you have bare wires or connectors, then use a y-branch like so to match your cables, RCA etc. stereo outputs of LF and RF
How do I know if the reciever is set to play back 7.1 Dolby Digital?
Check the receiver manual for it's decoding options and selection, but like I said before, you need sound encoded in Dobly 7.1 playing back on something (blueRay DVD most likely) and then monkey with the reciever setting to play it.
You'll know when you got it.
