yigit, the issue described in that topic is similar, maybe, even the same, but there's no solution for it.
Anyway, I don't want to use some kind of unofficial drivers and perform some kind of magic to make everything work,
It looks like that the cause of this sound problem is in buggy drivers, which have that pc beep option hidden, but enabled, and it is not a hardware problem, so the only thing I would really appreciate is an official driver without this bug available on lenovo website.
I'm sure that there're many people suffering from this problem (even on these forums there're many people who have it), so I think people from Lenovo staff should be interested in eliminating it.
I understand that most of you(moders & admins) are just volunteers there, so I don't have any claims against you, but some of you have relations with engineering team, and I would really appreciate if you will make them know about this problem.
mod edit: correction of my name.

we did that but don t work eather , if you read the topics maybe you knew that !!!!!! i'm so angry , nobody knows exactly where is the problem? what is strange is that is related a bit with the power management , if you change from blanced to energy star the noise sound becomes different ...

I just purchased a Y570 and I don't seem to have this problem. So it could be that the "newer" units have been fixed. I did have to tweak the EQ a bit because I thought the highs were too high, but other than that I don't have any kind of static or humming noise.
As the days/weeks go on, I'll post an update and the resolution here (if any).
Ok, I started noticing the noise when I plugged in a set of ear buds. I don't hear it using "over the ear" headphones but when I plugged in ear buds I noticed what I would call "oscillating white noise".
Changing the jack options from headphones to line out helps big time, but you can still hear it slightly if you listen for it. Overall, however, I don't think it's that big a deal. It doesn't interfere with music playback or gaming, although I did tweak my overall EQ settings which may have lessened the noise. If you have extremely sensitive hearing or an absolute perfectionist, it may be a problem (although I consider myself pretty **bleep** picky myself).
For reference, the earbuds I used were Jlabs 3M, and the over-ear headphones were Sony MDR-XD200's. I'm going to look for other ear phones and try them out later to see if there's a difference. I should also try external speakers too.
(BTW, I get the feeling that this is a hardware issue, not a driver issue. Unless someone can confirm that updating drivers actually fixed the problem. )

Hmm... it must be different sound issues. The sound I get isn't really crackling; it's more like white noise and it's very slight.
Or maybe the SRS system doesn't sound good with headphones, so it's a trade off between headphones/external speakers and the internal JBL's.
