[ardour-users] Track inputs and outputs, and monitoring

[Luc Tanguay]

Hello there CB,

I don't know your hardware, but here's what I've found for the Audigy -- 
the card I'm using (hope the ouput looks well).

Reference is from the package emu-tools-0.9.4, file README. I've added 
some labels.

Graphically, the mixers looks like this ( '*' represent volume controls):

Note that Analog_in is what ever you've selected as record source in 
your OSS mixer.
----

So you have an analog mixer (AC97) and a digital mixer (emu10k1). Ardour 
sees the pcm:capture and pcm:playback streams.

You can check a snapshot of my QAmix setup at 
http://www3.sympatico.ca/lucus/.  I tried to duplicate in QAmix the 
diagram above.
