Soundstorm / Realtek ALC650E
Apparently both the 8RDA+ and the standard 8RDA come with this same audio chip. What is the difference between the two motherboards then? Is it just the Dolby features of the southbridge? Is there any good software I can use with my 2-channel audio controller that is actually 5.1 I've discovered? I would like something more than the standard windows volume control if there is anything (i.e. equalizer). I'll probably switch to the onboard sound since I'm getting REALLY sick of the Audigy problem.

Oh and please forgive me if this has been answered somewhere else. Links will do just fine as a response :)

The Realtek 650 is just a CODEC (COder/DECoder). It's pretty much just a bunch of analog to digital and digital to analog converters, with a mixer and a serial interface (AC97). It does NOT do any processing. That's the job of the audio controller.

The main difference is that the board you have only has a basic audio controller. It's a pretty normal AC97 based solution. As such, it has minimal processing power.

The 8RDA+ uses nVidia's APU. This 5.1 solution uses fully fledged DSP. It can do DSP type tricks, such as EQ, Reverb and other effects, as well as on the fly AC3 encoding. Without that DSP, there's not really any easy way of doing these sort of things.

The 8RDA+ uses the ALC650E only for digital to analog conversion (and not at all if you use digital output),and the sound processing is done by the southbridge.

The 8RDA uses it (and a chunk of software based instructions) for all sound processing.

Dammit. Thanks guys. I wondered after I found out it actually does 6 channel even though on the board is listed as 2 channel. I just double checked Epox's page and it specifies the 8RDA as 6 channel. Got my hopes up :(
