In brief: I now own a set of Game Fury speakers from http://www.jazzspeakers.com I am building a 1GHz+ Athlon box at the moment (courtesy of a nice bank manager...) for use on my comp. degree next term and have tested the speakers with my old SB16 and SB64 cards, etc. but I cannot use the soundcard in my old machine (for various reasons mostly due to being "out of space") and so cannot yet play with it. The card uses the CMPCI driver to do audio, but I am assuming that it only currently handles 2.1 channels? What I would ideally want: 1). When no rear sounds are present or not available (e.g. 2 channel joint stereo mp3) play the sound to all speakers and duplicate sound to front/rear. 2). When 3d effects are present, play them properly - e.g. when using livid (when it gets to that stage) or when using LinDVD (if it will support that when it comes out at the end of this month or so). Since I do not get chance to follow linux sound developments more closely, can someone tell me the state of play so far. I would also like to thank Alan for answering my previous question - Alan, you work too hard :) Someone will try introducing me to ALSA :) I know a little about Alsa and I'm almost certain that OSS cannot handle 4 channels (I'll now be told that I'm wrong :) so I realise it will probably mean using Alsa, which is certainly no trouble/problem. I would prefer to use the cmpci stuff for the time being as it saves spending more on an sblive or somesuch (although I probably will buy an sblive at some point simply because sb have made several good moves recently - e.g. openal, etc.) Jon. -- Jonathan C.
