Updated to iTunes 10.5 today and now my Audio Playback IS TERRIBLE!!! HELP!!!!

So I was playing around with my computers and found out that this issue isn't caused by a VIA audio controller.

However, it may still be VIA related...

I swapped the sound cards in two of my systems. One card had a VIA controller (having issues) and the other had a Creative controller (not having issues). After the swap, the card with the VIA controller worked, but the card with the Creative controller didn't.

Now I've have another question to ask for those having problems with the audio in iTunes 10.5. Do you have a VIA chipset on the motherboard? Does your motherboard take an AMD processor? The two computers I have that are experiencing this issue have both AMD processors and VIA chipsets.

As for my other systems, which don't suffer from this issue, they have Intel processors and chipsets.

ASUS Motherboard with VIA Chipset and AMD XP2600 Processor

Just like mine. Only with a AMD XP 3200 processor.

I dont know what I have or anything like that I just want this fixed, First ios 5 turns my iphone 4 into a brick and now my Itunes sounds like robots are trying to smash out my speakers!!!!! *** Apple give us some help!!!!!!!!!!

I'm running mine on Windows XP Prof with an AMD processor as well and I'm having the same problem.

Having the same problem after updating to iTunes 10.5. Running XP Home Edition SP3 tried Microsoft updates no help. Seems to be happening with MP3 files. Import MP3's and try to play them and they sound horrible. Tried to covert them to ACC files using iTunes no help. Apple needs to fix this!!!!!

Only the "Purchased" music will play correctly. Any music currently on your PC wont, this includes "Radio" - sounds choppy / high pitched - horrible.

I'm having the same robot-sound issue.

My entire music collection is unlistenable.

Windows XP Pro SP3 32-bit

iTunes 10.5.0.142

Asus Motherboard A7N8X Deluxe

I'm using the onboard NVidia soundcard

AMD XP 2500 processor

+1 mp3 play fine in other software but not in iTunes and what is transfered to iphone is the same. Only just returned to Apple and endup with a bricked phone which took me 2 days to sort out due to ios 5 and lost everything .... now iTunes update doesn't work either! Doing well for the new guy!?

DeadRunner, I looked up the specs for your ASUS motherboard and see that you have a nVidia chipset. Today I installed iTunes on a fifth computer, this one using an AMD 64 Athlon X2 processor and a nVidia chipset. No problem with the audio there.

Judging by the motherboard specs left by you and others, I'm starting to think that it has something to do with the AMD XP processor.

This doesn't appear to be a hardware problem, it's a bug of itunes 10.5!! Even quicktime works fine with my mp3's in the same computer, stop switching soundboards please, this is a sofware BUG!! Apple please correct this ASAP

yeah, AMD XP processors seem to be the common thread, though I thought I might have read in another thread about a user on a Mac that was affected, but I'm not sure.

Im running Windows 7 on AMD

Has anyone been able to make contact with APPLE and get any kind of response that they are aware of the problem and are working on a fix? This support community is more like self help and I wonder if APPLE even looks at our posts. I can tell that they surely do not have any input or responses.

Same problem here folks NOT a driver/sound card problem as my music plays fine on other media players.

I too am running XP Pro with AMD processor

Come on APPLE hurry up and sort it out.
