Hi, I'm new here and just got my new 27" i5 Imac two weeks ago... now what I have noticed is that the same monitors (speakers) i had with my older imac (24") are constantly making a louder "white noise" than what they used to (didnt bother me that much but i definitely noticed a louder volume of white noise). The thing that really bothers me is that whenever i scroll the mouse, or click and drag an object in photoshop or something the monitors are making a really noticeable disturbing scratching sound sound ...just cant seem to make it stop..its so annoying .. i also tried to record something and the imac recorded it in a really low volume and unstable wave (volume going up and down). so i figured well obivously the soundcard of the new imac was real bad..so got me an external soundcard, Emagic emi6|2m and i figured it would solve the problem. installed the soundcard, and played a song and suddenly a high pitch noise, kinda loud and really disturbing, started coming from the speakers. 2 seconds after i pauseded the song, the sound stopped. play the song, the noise comes, stop the song, noise stop after 2 seconds. if i open up Logic, the sound just starts no matter what. quit Logic and the sound stops. just now i opened up a youtube video and the sound just started going off even after i paused the video. now the sound comes everytime i choose the Emagic soundcard in the sound preferences. its kinda real loud and its bothering me so much, i cant seem to make it go away and definitely cant work with it. When i tried installing the soundcard on my brother's laptop windows with the same speakers, everything was fine and it played perfect with no noise. whaaaaat can i possibly do, this actually really frustrates me....whats wrong with the computer? something with electricity?
