I'm using a very inexpensive C-Media CM8738 PCI card. This has speaker outputs for 5.1 speakers and also an S/PDIF passthrough. It's supported by alsa and although I don't have every bug ironed out (I'm fairly new to MythTV myself) it was easy to switch the surround sound on in xine to use the card's decoder.

Sounds like you want to use your own speakers. Shouldn't be hard apart from getting the right connections. I went for a set of 5.1 speakers by Altec Lansing. They plug straight into the card. A nice feature is that they are controlled by IR remote, so I've programmed my learning remote to control the volume by turning the speakers up and down rather than getting Myth to alter the volume.
