I have noticed on my brand new Precision 5550 there is a noticeable vibration noise when the volume is above roughly 60%. The noise appears about 350-500Hz it is like a membrane vibration, which disappears if I turn upside down the computer.

This noise is annoying me because it appears when Windows give the attention sound, or during the video call (when another presenter is speaking). I have the latest audio driver, I never drop-down or hit the laptop.

I paid 3300$ for this machine, and I think DELL is far away from premium products, my last Laptop was a 1200$ HP envy with Bang and Olufsen sound system which was much better than this.

When I want to get help from DELL Support, they didn't want to help me only send me the local technical support phone number.

I'm a little bit sad and disappointed because I hope more for that money....

Here is my problem: https://drive.google.com/file/d/1wN5z3-EoxmCVfPtmObNynaNOMLaPa5K-/view?usp=sharing

I have the exact same issue and I'm able to reproduce consistently using the piano app, multiple keys cause resonating vibrations. I also don't think such an expensive unit should have such an issue.

Multiple support technicians have tried to resolve the issue by reinstalling drivers or sound application Dell MaxxAudio Pro application. I've had the mainboard and speakers replaced. Reinstalled OS because support wanted me to (could start all over installing software). Now I'm waiting for a replacement unit, which will arrive in a month, I'm lucky the support package was part of the deal. In the mean time I am working on my old laptop, so I'll not spend time installing software which I may reinstall on the replacement unit again.

The membrane vibration according to me is a hardware design fault which I presume is part of the casing or keyboard, because speakers and mainboard have been replaced. I was reïnstalling the OS, and while the sound drivers were not installed, the sound was without vibrations, though also without bass. So my conclusion is that the speakers produce a certain amount of vibrations that cause something in the unit to vibrate.

I guess Dell Support Protocols don't account for this type of fault. The 5550 having these premium speakers and also the speakers pointing upward, is fairly new. My 12 year old Dell laptop also had upward facing speakers, but they don't have the same bass quality the new ones do.

I am having the exact issue with my Precision 5550.  If I am on a zoom or teams call the audio is terrible with this vibration/crackling sound.  It occurs as all volumes.  You can even hear it when the windows chime goes off.

The tech replaced the speakers today, but the problem is still there.  The tech wanted to replace the motherboard so that will get done tomorrow, but I am doubtful that will resolve the issue based on what I have read below.

I have had the computer about 45 days and am dissappointed with this laptop.  Hopefully Dell will take it back if the motherboard switch out doesn't fix it.

Tech came to replace the motherboard.  After about an hour he comes into my office and says the function keys and trackpad are not working with the new motherboard.  As I am talking to him I notice the box that the new motherboard is in has "refurbished" stamped all over it!  So Dell sends a refurbished motherboard to replace the motherboard in my brand new laptop.  I was not happy.  At any rate, the tech can not get the new refurbished board to work and installs the original motherboard. 

The audio crackling is still there, but at least the function keys and trackpad went back to working with the original board.

From what I can tell, this is a flaw in the 5550 machines and something is vibrating to cause the crackling sound.  I am now working with Dell on a refund.  Don't buy this machine if you plan on using it for online meetings or expect to use the audio.

Hi this is Justin from Dell Support. Rahul is away right now so I will ping him in a moment and ask him to update you.

As for refurbished parts, that's just the way it's always been, for many years now. The industry, and many other industries do it the same way. We do not have any replacement parts labeled 'new'. ^JKC

Just  got this from Dell!  If they have to repair your brand new laptop beware as the don't have any parts that are new so your machine will be repaired using refurbished parts.

Still nothing from Dell and no way to actually talk to anyone other than email.

The same happens to me. In fact, I had to change the 'bass / grave' notification sounds that Windows brings by default because they were heard very badly. Momentarily for Zoom calls or when watching Netflix you can place an object on the keys on the right side of the keyboard so that they do not vibrate.

If they managed to solve the problem, let me know, I still have several months of guarantee.
