Distorted Sound

I own a Dell Laptop. It's relatively new (less than a year old).

Today, I started iTunes to play some songs but the sound was distorted and mushy.

I thought it was iTunes that was giving me the trouble. So I reinstalled it. But that didn't do anything

I reinstalled WMA but that didn't do anything either.

I panicked and went into Control Panel> Sound and Audio devices deleted all the codecs (about 10 different kinds) to see if that would do anything. Well, didn't do a thing. Now I regret why I deleted all the codecs.

So far when the every volume bar is up, and when I am playing any mp3 or wma files, my computer plays a very choppy and mushy sound.

But the funny thing is that every avi file I have still plays normal clear sound when every volume bar is up. Maybe that's what made me think that it's a codec problem not a driver problem.

Well here are the things that I'd like to know:

1. Does it matter that I went into the control panel and deleted all the different codecs I had? If they matter, how can I get them back?

2. What can I do to fix this problem of distorted mushy sound from mp3 or wma files?

I'd appreciate if someone can tell me how to fix my problem. Thanks.

The common cure.

In reply to: Distorted Sound

Set the IDE channels all to PIO, OK your way out, then go back in and change them back to DMA if available.

It's a known XP issue or bug and easy to do.

I am not so good with twicking with the computer settings.

I'd really appreciate it if you could explain and instruct me how to do it.

Thank you.

No twicking required. Read this aritcle on how to.

I did as you suggested. But nothing has changed.

I don't know what to do anymore. The only thing that I can think of now is that my laptop speaker system had a melt down and got damaged (I don't know whether that makes any sense...haha).

Now I think about it, maybe I had left my laptop speaker on full blast too long and too often.

It still sounds alright when its volume level is about 50%.

If you have any other suggestions in terms of reviving my dying speakers on my laptop. Please let me know. Thanks so much for your help, Bob.

Try external speakers.

In reply to: well...

It's good we got that DMA item out of the way. It's a common cause of many audio issues.

If not external speakers, headphones or earbuds will do.
