Scratchy, distorted, garbled sound from MP3s files

I'm having similar problem. mp3 songs imported into iTunes up through 10.4.x worked fine....I downloaded 10.5, and suddenly all imported mp3 songs are garbled. Many play fine, and purchased songs seem unaffected. I've deleted affected songs and re-imported (the original mp3 files sound fine in Real Player), but produce the same garbled sound in iTunes. What is going on, anybody know how to fix?

Many people are having this issue. Hopefully a fix arrives soon.

After reviewing all comments, it appears that this issue is squarely with the 10.5 upgrade that Apple did on I tunes. I have done all the uninstall and re-install that you can do. Songs play fine on some, terrible on others, but yet they all will play on Windows Media Player. I can't believe it is the chipset for those that AMD processors, because everything was fine on the 10.4. So, Apple please fix this or offer us a way to uninstall from the 10.5 to the 10.4 where everything should be okay. Awaiting your reply with thousands of others!

😠😠😠

Same problem here, uninstalled and reinstalled with no luck, please fix soon. I love itunes

I have been trying to fix this but at no avail....apple please fix these issues!!! I love itunes, but not when it isnt working well....wow ! this is pretty unreliable ! Like all the other computer products! I guess there is no difference with apple vrs ...... anyone...gone are the days of NO PROBLEMS!!!

Update the software so we can restore our faith in APPLE again...

Me too, Bud. As brilliant as the Apple hardware is, their software would have been better left to Microsoft.

I downloaded new version, 10.5.1.42, and problem appears to be addressed and fixed. I've sampled songs that were garbled, and now they're playing fine again.

Newest update finally fixed it!!!!!!!! It should not have taken so long, but I am glad it's fixed! Now Apple needs to make Match work on XP computers and they will be back in my good graces!
