clipping sound on new iMac when Logix X is running
I just got the new iMac that was released two weeks ago yesterday. All I did was set it up with Logic X, Main Stage, and Aperture all from the app store. nothing else was put on it. I opened up logic just to check it out and see how much faster the performance would be. I just wanted to give it a quick test and played some apple loops I immideatly noticed it was making a clipping sound randomly. The meters were not peaking everything was in the green and if you turned down the gain the clipping just got quiteter. I called apple support thinking it was a hardware issue. They had me do some trouble shooting like playing the same loops through quicktime and the clipping persisted. they also had me play a youtube video to see if I could hear the clipping. It wasn't as noticible but it was there. Apple decided that it would be a good idea to reformat the computer tomorrow and start over. Sounded fine to me seeing how I didn't have much installed yet. I did a little more trouble shooting on my own after I got off the phone with apple. First I made a copy of three apple loops and put them on my desktop then restarted the computer. Then after a fresh restart and nothing running I opened one of the apple loops off the desktop with quicktime player and it sounded great no clipping. Same with You Tube. I then opened Logic Pro X. Did nothing with it but minimize it. I then went back to quick time player and tried to play the loop again. This time the clipping was back. Same with You Tube.
My conclusion for some reason when logic is running the audio makes a random clipping sound no matter what audio program you play the audio through. (Clipping sound comes out of the internal speakers as well as headphones)
All of my software is up to date.
I am running:
27" iMac
3.5GHz Intel Core i7
16 GB 1600 MHz DDR3
If anybody has experienced this same problem or has any recomendations they would be greatly appreciated.
I am going to reformat in the morning and try and start again.
I will post my results
Thank you,
