I just got a laptop, an HP one. :S But it's good enough for me.

When I'm listening to music, the sound volume seems to waiver, and I know it's not the song, but I'm not sure if it's me or not.
If it is the speakers, anyone suggest anything?
I don't want to tell my mom about it or she'll be angry that I "broke" it. 

do you have a warranty? can you take it to where you bought it

Try to reinstall the soundcard
*Edit
I purchased an HP Laptop for my daughter, the HP website is pretty good, make sure you install the updates.

I. uhm. Didn't get a warranty. It was during the black friday sale, and I had to buy it while my mother was at another store, so I said no on the billion dollar warranty.  

Good idea Denis! Psh. Can't believe I didn't even think of that.
