Connecting laptop with mixer panel

[JDemonie]

Hi,

I need to connect my laptop with a mixer panel to play some keyboard parts live.

2 questions:

I tried this: the mini-jack out of my computer to 'tape in' on the mixer panel,
this worked, but theres this noise you can clearly hear when no other instruments are playing.
Could this be because of the room not being grounded (not sure how to put that)?

I have a Tascam US-122 (external soundcard), should I use that instead of the mini-jack out?
If yes: how?! I guess the Tascam doesn't get any sound from Ableton, just by putting the
USB-cable in. But if the Tascam needs some other input, than the only way to get there is again
that same mini-jack right?

Anyone?

i bet if you read the manual it would completely answer your questions...

No need to get sarcastic smartass.

It's not mine, that's why I asked it here.

If you go to Live preferences, have a look at the Audio-Settings. There you can select the Audio output (i.e. which device Live sends audio to). Make sure you've connected your Tascam to your computer before you launch Live.

After having selected the Tascam as audio-output, you can define which output Live sends audio to, either on the Master track or on each track individually.

You'll see the physical outputs of your interface (Tascam, in your case) represented as '1/2' (stereo), '1' (mono, using channel 1) or '2' (mono, using channel 2).

I hope this helped.
