Hey there I am looking for some help on how to get my surround sound speakers working on my computer.
The surround sound system uses 4x 3.5 mm headphone jacks. (it looks something like this:
(with the USB being used for power only)
What I am trying to do is run those through a receiver or converter so that I can convert them to a single toslink SPDIF optical cable that I can run into the back of my iMac.
I have found this device which can do it for 5.1 one, but have been unable to find a similar device for 7.1: http://www.ebay.com/itm/Optical-SPDIF-Coaxial-Dolby-AC3-DTS-Digital-to-5-1-2-1-CH-Analog-Audio-Decoder-/261103761583
Sony also makes a receiver that I think should be able to do it in theory (http://store.sony.ca/7.2channel-4k-wifi-network-a-v-receiver-zid31-STRDN1040/cat-31-catid-All-Receivers-Speakers-and-Stereo-Components), however it does not have 3.5mm headphone jacks in the back, rather the large analogue audio inputs. Is there some sort of adapter that I can use with this device?
I currently am using the Diamond Xtreme 7.1 USB sound card, however, it has been having severe driver problems since the release of Mavericks and has never had the greatest sound to begin with. Which is why I am looking at these alternative options that can run directly into the audio port rather than depending on USB audio drivers which may or may not work very well.
Any other advice would be very welcome, I have been googling for hours trying to figure this out but I am more than likely just googling the wrong thing.
