X1 Carbon 2015 : Cracking sound speaker, especially with Dolby on (and other issues)

2015-04-20, 18:27 PM

Hi all,

 

I just received my new X1 Carbon 2015. This is the first time I purchase a Lenovo Device after years with Dell.

 

Unfortunately, the sound quality is horrible, but I am not sure if this is by design of if the laptop is faulty..

 

The sound is very bad when it is coming from the speakers, especially the left speaker: the sound is cracking and saturating. This is especially true when the Dolby is on, and you clearly hear the problem with standard Windows event sounds (for example the sound you can hear when you adjust the volume with the slide on the sound icon next to the clock), or any warning sound.

No problem if I use an headset.

 

Am I alone with that issue?

 

Even if the device looks great, I have to say that I am overall disappointed by the laptop quality, especially regarding the cost of that device (this is the Core i7 with QHD touchscreen and 512GB PciE SSD):

- When I received it last week, the left button from the trackpad was stuck (impossible to use). I had to gently scratch the side of the trackpad button to release the button. Probably some remains of the manufacturing blocking the button.

- Then I noticed that sound issue.

- And finally yesterday, I discovered a spot on the bottom right of the screen. Not a dead pixel, but a clear spot behind the pixels, 1 square millimeter,  reflecting the backlight.

 

Thanks

 

Pierre

I have the exact same problem with the speakers, particularly the left one. It sounds totally distorted, cracking, and tinny when playing almost anything. As the OP pointed out, it's even worse with Dolby enabled. I will be calling customer support and/or service about this.

 

I don't have any of the other problems the OP is experiencing. Except for the horrible, obviously broken sound quality - my new X1 Carbon 2015 has been a pretty good experience.

Thanks jimre for your feedback.

I am going to contact the customer support too, but I wanted to check first if I am alone with that issue. Apparently not !

I'll keep the thread updated.

Just had the IBM service tech at my house to replace the left speaker (I had purchased on-site service contract). He replaced it with a new one, and it now sounds normal - the distorted cracking & buzzing is gone. There appeared to be some tiny nicks or cracks on the original speaker element, which may have caused the problem.

 

The process was fairly painless. Lenovo had the part in stock, shipped it to a local tech, who scheduled the service call within a day.

 

The sound quality of course still isn't great without external speakers or headphones - these are just tiny little ultrabook speakers, after all. But at least now the sound from the built-in speakers meets my expectations, and doesn't make me cringe when I hear it. Once again enjoying my new Carbon X1...

Sounds good !

 

I also called the tech support yesterday, and they are sending a technician next week to change the speakers (and the screen too because of the spot I have). I hope this will fix the issue too.

My XI Carbon Gen 7 has the same issue.  Left speaker making very tinny sound when I just adjust the volume slider or anything.  one time I rebooted and the problem went away but now it's back and driving me crazy.  If not for that, these speakers sound awesome.  I do not have the problem with headphones.  However with headphones I don't get enough volume even at 100%.
