Using headphones on my Alienware M11X

Ok so I got my Alienware about 2 weeks ago now I think and had a problem with the 'f' key ... Dell where really helpful and someone came out the next day and put in a whole new keyboard.
The only issue I am noticing now is using headphones to listen to music. It seems that the sounds levels change throughout the song not drastically but definitely noticeably I was just wondering if anyone else had came across this or was able to give any help on working out the problem?
Thanks

 

I haven't noticed that. First, try another music playing program to verify that isn't the culprit.

 

Check if the driver have a problem? or maybe your headphones are not okay? by the way what headphones are you using?

 

I am using my iPhone headphones which are fine with my iPhone and also I have tried a few different music players and it seems to pretty much be the same all round.
It is quite subtle but it is really annoying it just sounds like the levels are very slightly moving about.

 

it's probly the headphone one time i had a iphone head phone it idndt work on my laptop i tryed a diffrent headphone on the laptop it worked

 

Just tried some different headphones and have exactly the same issue think I might ring support again and see if they can sort something out!

 

Does it in both headphone jacks?

 

Yeah it is the same in both which I thought made it kind of strange? Don't know if they are corrected in any way

 

They are. I don't think there's a replaceable audio component on the motherboard either, so my guess is that Dell is going to have to replace the motherboard. Call them and have them troubleshoot the issue.

 

Ah man I hope that isn't what it comes down to. I will keep you updated when I have spoken to them.

 

When I had the crackling audio issue they just replaced the unit

Definitely no separate audio component
