TerraTec Aureon 7.1 PCI Sound Card
 

erratec’s Aureon 7.1 PCI is a low-cost soundcard that features Dolby
Digital Live encoding. So if you can look past its £39.99 price ticket you
can snap up a relatively powerful audio solution for equipping a general
desktop computer with top-end surround sound technology. Having said that,
you should note that the maximum number of channels that Dolby Digital Live
can output is actually 5.1 - the 7.1 refers to the Aureon’s number of
analogue outputs.
