Sound was easy with alsa. I simply ran (as root) alsaconf and hit enter a couple of times :) The end result was a few lines added to /etc/modules.conf which read:
alias char-major-116 snd alias snd-card-0 snd-card-cs4231 alias char-major-14 soundcore alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss options snd snd_major=116 snd_cards_limit=1 options snd-card-cs4231 snd_id=card1 snd_index=0 snd_port=0x530 snd_dma1=1 snd_dma2=3 snd_irq=5I suspect that simply adding these lines to /etc/modules.conf would bring the sound into useful complience, oh, you also have to do an rcalsasound start to activate the sound card. This is done automagically by alsaconf.
