Re: [linux-audio-user] KMix for Audiophile 24/96

For a few months now I've been using Audacity with an on-board sound circuit, the ASUS A7N8X motherboard's onboard AC97 audio controller. It's been OK, but maybe I can get a better sound with an M-Audio Audiophile 24/96. I got one used, with no documentation, and I can't see any at the M-Audio site either. My problem is I don't understand the KMix mixer for the Audiophile 24/96. I'm just a simple guitar player, not an audio technician. The AC97's mixer with it's Volume, PCM, LineIN, and LineGain ... it was easy to figure out. But this mixer lists stuff I've no idea what it means. Could anyone tell me what these KMix settings do?
