Note about Mac:
It is not able to decode AC3 or DTS streams. It is a simple sound card with 6 or 8 output channels and a few input channels. Plugging an optical cable into the S/PDIF input if your card has one, will not cause decoded audio to come out of the outputs, nor can you get multi-channel output by sending an encoded 5.1 stream from your Mac. The software you use must support built-in 5.1 decoding to get multi-channel output out of your sound card.
Also,
don't expect to get surround from stereo material. An application must address all six or eight output channels to produce output on all speakers. When playing stereo sound, i.e. what almost every normal Mac application produces, only your front left & right speakers will be used, not even your subwoofer unless your sound system has bass management — which it probably doesn't unless it is high-end. There are ways to get
upmixing in MPlayer and even system-level upmixing by
using Jack, but neither methods are really practical and will only produce ‘fake’ surround.
More about the S/PDIF output: as far as I can tell, it only supports 8 output channels, and on most cards only 6 of those are connected. There is
no separate S/PDIF output channel, which is why you won't see it in the OS X control panel or Audio Midi Setup. The S/PDIF can only be turned on and off and is just a hardwired copy of the signal that goes to the
Front channel. You can get AC3/DTS passthrough by configuring your media application to pass through the undecoded 5.1 stream. This makes the card's S/PDIF only really useful on a ‘hackintosh’ that doesn't have a built-in S/PDIF, because on a real Mac it's much simpler and cheaper to use the Mac's built-in S/PDIF through a 3.5mm jack adapter.
FAQ:
A: this sound card could be good to record a guitar with a microphone connected to mic-in?
Q: The item can do it. However, the Mic-in can enchance AND increase the volume of the audio input. So the volume of the guitar can't be too high or it would lose the quality.
