Recording help please

Hey so im running the new audacity on windows vista i can quite easliy record one track, that works fine, but if i add another track that becomes very quite, if not slient, and randomly spikes. When it does spike i can hear what i am trying to record, so it is picking some of the recording up.

Any ideas???

Help much appreciated

Any time Windows seems to be adjusting its own levels or quality, you should look for “Enhanced Services” and turn them off.

I know we posted official instructions for this, but I can’t find them.

They’re in the FAQ:
