Updated To Mavericks, Now Audio Quality Blows.

Same exact issue. I thought I had blown my speakers somehow. I was about to make an appointment at the genius bar, but I figured I'd see if other people were having this issue as well. The only thing I've changed on my computer since the crappy sound quality is the update to iTunes and Mavericks.

I messed around with the equalizer, but it only fixed it temporarily. I would replay the song and my speakers sounded blown again.

Glad I'm not the only one, hopefully Apple will put out a fix soon!

Having the same audio issues. After upgrading to Mavericks and I am having audio issues watching movies from iTunes. Have not yet tried listening to any music from iTunes since installing Mavericks.

Audio issues resemble that of skipping CD to a dusty record, but the audio continues playing. I can get it to clear up by advancing to the next movie in the list. The next movie, the audio sounds fine. I then can skip back to previous movie at the same scene and it will be fine for about 10-15 mins then it will slowly start to get worse. I am watching Star Trek Into Darkness, it is an offical digital copy download from iTunes store. Running a 2012 15" MacBook Pro.

I had the same problem, but try to download again Itunes from apple.com that's how i fixed it

Exact same problem, I updated to Mavericks first and realised this problem - then I updated to the new iTunes thinking this was released to fix the problem but I'm still having it.

I like my music on the Hip Hop equalizer (it just sounds better) and now it sounds like my speakers have popped. If I use my MacBook speakers I can't tell as much but that's mainly because they're no where as good as my desktop ones.

It's like bass is coming out the satellites rather than the subwoofer which is super annoying. Hope Apple engineers are on this already working out a fix because it is needed ASAP.

Redownload iTunes from Apple website. Apple.com and that will solve the speaker issues we've all been expiriencing. Don't know why this glitch occurred however that is the solution to the problem. Redownload itunes from apple.com

Thanks pal

After my upgrade (MacPro 2008) my external speakers will not work. Only plays from the internal speaker.

You can also just delete the iTunes plist files. That will keep you from having to download iTunes again.

If I reinstall iTunes will it mess up my music? And same for if i delete the iTunes playlist files?

As in the play count, playlists and all that, and will i have to bring it all back into iTunes?

Thinking about doing it as people saying that fixes it but not sure if I should wait for an iTunes update to avoid the above.

Deleting .plist files wil not alter you music, play count. It's a preference list, not play list file. This is actually a very common troubleshooting step used by apple all the time.

Also, reinstalling iTunes will not mess up your music. It will use the same Library.

Deleting these two files and restarting fixed the issues for me. Thanks a bunch! I've also added your solution to another thread regarding the same issue ( https://discussions.apple.com/thread/5471381?answerId=23549207022#23549207022 )

Again, thanks a bunch.

Hi, just for the record, how can we submit a bug report to Apple? bugreport.apple.com?

I used it twice (once for this very bug, and some time ago for something else), but it does not seem that Apple had taken much care about my reports... Am I using the right tool? Or is there something else more suited to report bugs like that?

Thanks (and I'll try the trick of reinstalling iTunes tonight, I hope it'll work!)

It somehow worked for me. I turned off the equalizer and it worked.
