    At the moment it is not possible and won't be until a laptop is released that can encode AC3 in realtime. We'll probably see the first mobile chipset capable of doing this from nVidia, although they have been dawdling with their mobile nForce implementation.

    Edit - I'm guessing the problem might lie with AMD. Until they get CPU/memory subsystem power consumption down, I'm not sure that nV will even consider releasing a fully integrated, mobile core-logic solution as powerful as the nForce 3P.

    DVD playback with full surround via S/PDIF should be fine, however.

    The nForce 2 sound has a real time AC3 encoder, but that's the only one that I know of. The rest will only give you stereo sound (unless you're using the amp's pro logic, but that's the amp rather than the sound card). You can watch DVDs in surround sound using the AC3 passthrough facility, but games will only be in stereo I'm afraid.

    There are USB 'soundcard' type affairs which offer breakout box connectivity for RCA/Phono in and out with up to 96/24 in/out and possibly pass through. Off the top of my head, can't recall any manufacturers but rumour had it that it could pass a 48kHz stream from a DVD via Win/PowerDVD.

    Maybe check Roland?

    Creative do one, but I'm not sure how good it is.

    I've since looked at my brother's dell laptop and it appears that he has a digital sound output on the same splitter cable as his svideo output. Unfortunately I don't have my amp here to test it :(

    I have an Abit USB thingy that works well. It's a little box and has optical in and out and can do 5.1. Got it off Dabs I think.
