Well, there you go. You shouldn't plug your main out into the input of your m-audio. WHen you arm a track for recording and turn on input monitoring, the signal is being fed back in. You should use a separate bus to feed the input of your sound card so that only the signals you want will go there.

I monitor and listen back through the M-audio headphone out.

How do you have your sound card connected to and from your mixer?

As I said in my earlier post, when I play audio files through this sound card they are fine, no noise, however, when I launch Sonar and arm the track, there is a low, slow pulsing buz. When I hit the record key, the buz seems to disappear. Then after I've recorded several tracks another low constant hum can be heard. Any suggestions? Jim McAuslan . Its not too obtrusive, and when I arm the track ----- Original Message ----- From: Phil Muir To: ddots-l@xxxxxxxxxxxxx Sent: Sunday, June 11, 2006 6:10 AM Subject: [ddots-l] Re: noisy sonar Jim, what sound card are you using in order to playback audio outside of Sonar? If you are exclusively using the M-audio in Sonar and a second sound card to play audio in other applications then, it could be the M-audio.

I thought it might be my M-audio fw 4-10 sound card, but when playing other sound files, everything sounds clean as a whistle. Could this hum be something to do with my pc?
