Hi,
I found the problem in the end was that i needed to download the full driver packge for alsa and install then run a script all as per the instructions that came in the tarball and then alsaconf found my card and set everything up for me
Was a bit puzzled though why the Slackware 9.1 install from the CD was missing my card.
Oh well, working in the end
Thanks for showing interest in my problem.
Warm Regards,
Chris
