As far as I know, Audacity won't work well with jack, so you will have
to use alsa for that.
It might help if we knew how you set up jack and in which order you
start your programs (jack/ardour).
I'm also assuming that you did not install any extra programs like
pulseaudio, and that you are running a puredyne system.
If you like, you could give this a try, to see if it works.
If it does, it's just a matter of finding the right settings for you:
Open up a terminal and run some commands.
First find out which number your card has with this command:
ls /proc/asound/cards
The result would be something like this:
"0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xf9200000 irq 45
1 [Live ]: EMU10K1 - SB Live! [SB0105]
SB Live! [SB0105] (rev.7, serial:0x806b1102)"
Let's say your m-audio card was marked as number 0.
Start jack in the terminal with this command:
jackd -d alsa -d hw:0
If it was marked number 1, you would do
jackd -d alsa -d hw:1
Now, the result should end with something like this:
....
ALSA: final selected sample format for capture: 16bit little-endian
ALSA: use 2 periods for capture
ALSA: final selected sample format for playback: 16bit little-endian
ALSA: use 2 periods for playback
Keep the terminal open and start Ardour.
First import/open a sound file to see if you can get playback.
(Make sure that you have not set mix to input yet)
If yes, then you should also be able to record.
You will just need to select the right input from ardour.
Finally use Ctrl-c to stop jack in the terminal.
Each time you restart your computer, your soundcards load in any given
order, so you will normally need to choose the right card in qjackctrl
before you start jack.
About FastTrack:
The fasttrack has a direct output for whatever goes in, meaning the
sound never passes through the computer before you hear it in your
headphones.
This is what happens when you set mix to input.
If you for instance use a soft-amp for your guitar in realtime, you
would not want to use the direct output, but instead monitor yourself
from the computer.
If you are not using any effects in realtime, while you record, you
won't need to have low latency in jack settings, since you have the
direct output from your card. In this case you can set the buffersize
(frames/period) really high, which gives you some performance
improvement.
Hope it works out.
