Thank you very much for your help, Mark. As you can probably tell,
I'm a linux newbie (about 6 months), and I'm very appreciative of the
forum's help. When I first installed FC3, I got no sound at all, but
with help managed to install ALSA and the module I needed for my
on-board emu10k1x chip. So far, so good. Now if I could only get
audio-stream recording going!
Regards,
Ron
