^^ You can use a 3.5mm to RCA cable to connect the onboard audio to the amp. The onboard audio is not likely to be anything good to write home about, though.
To get better results you can either:
- Get a soundcard and use the analogue-outs of the soundcard to feed your amp, or
- Get a DAC. You can get a digital signal out of the computer via USB or Optical (this motherboard does not have a digital coaxial out). The analogue out of the DAC can be used to feed signal to the amp.
BTW, by "amp", do you mean 2-channel amp or a receiver? I could be wrong, but something tells me you have an AVR. If you're planning to get audio out to an AVR, a HDMI cable will do the job.
