W540 Speaker hissing sound

I bought a new Thinkpad W540.

 

Everything run well. But I found a problem.

 

Once I played any sound, I could hear the spearker hissing sound, it is very annoying.

 

Could you please help me? Or where can I test the spearker by tech support.

 

I am in Boston, MA, USA.

 

Thank you.

Re: W540 Speaker hissing sound

Same as below message posted bfore:

 

OS: Win7 pro

Driver: Realtek 6.0.1.7071

 

Prior to installing the Realtek driver, the noise was constantly on during OS.

 

Muting the speakers (or volume 0) stops the noise completely. Muting or unmuting the microphone has no effect.

The noise is not transmitted via external speakers or headphones, but is hearable on the internal speakers while external speakers/headphones are connected (yet, again only whenever a sound is played).

 

Having the machine plugged in or not has no effect on the occurence of the noise.

Re: W540 Speaker hissing sound

Hi.

 

Just got my brand new Lenovo W540 myself, and experience the same sound, regarding the speakers.

 

On power up, when im in BIOS, and so on. But when OS is loaded, and the drivers kicks in, it stops. Except from

once I played any sound or browse the web, I can hear the speaker hissing sound

Also have the latest BIOS update.

 

Im running on Windows 8.1

Re: W540 Speaker hissing sound

Hi,

 

Absoulately, I have no idea for this problem.

 

Three days ago, I contact the technology support through telephone, they just ask some questions about my W540's problems, no resolution were proviede to me.

 

The suggested me that you can return it if you feel bad or not like it.

 

Then, I talked with post sales from Lenovo about return in the form of chat on the Lenovo websit, they give a idea that I return this one and right now buy a new one. As you known, maybe, long time I received this computer from pre-order, at least 3 weeks, need to shipmment from China. In other side, I need this computer to complete my work since my former computer is dead. 

 

Hence, I just accept current condition of my computer. I think I have fitted to this computer. I always mute my compuer due to no noise in office. It is does not matter for the hissing sound.

 

Whatever, you make your own choice, return or remain, it is up to you. After all, the price is very high. I cost nearly 2000 USD.

 

Thank you.

Re: W540 Speaker hissing sound

Has anyone found a remedy to this problem?  It seems like software fix is feasible because the hissing sound varies depending on the volume set in Windows.  When the speaker is muted, it goes away completely.  When the volume is 0, but not muted, the hiss is a little audible.  With the volume set to any amount greater than 0, the hiss is very noticeable.

 

And now that I've noticed the hissing, its pretty unbearable.

Re: W540 Speaker hissing sound

Thanks for the update.  I'm most likely going to hold on to it since I can't really go through the process of sourcing a different computer right now.

 

I'll see if any combination of volume controls help mute this hissing sound and I'll let everyone know if I find something.  I noticed that you can cover up the speaker holes with your fingers and that blocks out the hissing sound without changing the the sound dynamics too much.  Perhaps a custom shim to plug up the speaker holes is an option I will look into.

Re: W540 Speaker hissing sound

Personally, Realtek chipsets (audio and wifi) are mediocre, to put generously.

Ask for Conexant (or better, Wolfson) in future machines.

Re: W540 Speaker hissing sound

Just a heads up for anyone following this problem.  The T440s also has this issue and there is an ongoing thread here: http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T440s-speaker-noise/td-p/1339883

 

If Lenovo does come up with a fix, I would not be surprised if it is applicable for the W540.

Re: W540 Speaker hissing sound

You know what, let's expand the range of affected machines a bit.

My Ideapad Flex 15 does exactly the same thing, over speakers and headphones.

No amount of driver/software fiddling gets rid of this, aside from setting the volume to zero or muting it.
