Sound Cutting In and Out!
I'm having a sound-related issue:
EVERY sound--except for the startup sound--is now cutting in and out/stuttering on my iMac:
- Music playback stutters
- sound does not play during previewing video
- Sound cuts in/out during video playback in QT
- alert sounds stutter
- various sounds within other programs (adium, aol, etc) stutter and cut in and out.
In addition, the volume buttons on my keyboard are showing some lag, and are sometimes not responsive. EG: if you tap 3-4 times briskly to raise the volume, it may not respond, and then all three "blips" will occur in a bunch to signify the volume has been raised.
I recently downloaded the recent OSX security update/itunes update, as well as an HP print driver update, but that was days ago, and this problem only started RIGHT NOW.
My only lead is this: I visited some sort of audio recording/karaoke page on MySpace to view something, and the audio started acting glitchy. I'm not saying this act was responsible for the current issues, but it did seem to occur at about the same time I noticed these problems.
Lastly, you should know I've ALREADY tried the following:
- verifying/repairing disk after starting up from the install CD
- verifying/repairing permissions after starting up from the install CD
- Resetting my PRAM
- I've checked my temps (for fear of an overheat), but all my temps seem to be under 60 celsius which is normal according to iStat Pro, and these boards.
Any thoughts on this one? Thanks VERY MUCH in advance!
