Buzzing Sound on Microphone

I have the same problem with my 700m. My guess it's a shielding problem internally as I have tried a few different microphones.

Short of sending it back, perhaps a USB headset is the solution. Dell should pay for it however .

Turns out that deselecting the Microphone boost setting from the control panel solved the problem.

I have the same problem of buzzing.   Anyone have an answer?

That may be great, re the USB and the audio card, but I paid for a working jack.  I had to go out and buy a USB headset for 90 buck and then I wasted 20 bucks on the Walmart set which I can't take back because I threw out the receipt and the box it came in.  So I am out $110 plus my TIME....the time is what really grabs me....Nobody gives a Fiddler's (blank) about our time.....they get paid, we get paid, but who pays us when we have to fool arouind with something as simple as a ten cent mic plug and a garbage grounding job.  Who pays us for our lost time?????? Dell????????

You will never get it fixed!!!!!  It is a design flaw!!!!!!

I agree. I'm just going to have the technician take care of it. it's not worth my time nor my money.

Yes, you are wise to have a tech fix the problem, but this falls squarely in the lap of Dell.  They know about the flaw and yet they continue to produce these machines a record rate.  I have it from a good source that they never figured users would be using those imputs with USB available, but they guessed wrong.   And, one other thing...if you break a USB headset, it will set you back a lot more than the tradition 1/8" plugs, no?

 

Look for posts from other users.

I never had any problem with my 600m, and I liked the fact it had an external mic and I wouldn't have to use a headset. I primarily use the mic with Skype, but the receiving end hear a buzzing sound everytime I talk into it. Pretty annoying...

Hello there!

 

I read your post with interest.   

My point is that somewhere along the line, someone with a little electronics zachel should have known that you have to ground the plug to the chassis.   Now, if they say that the plastic would prevent a good ground and this is true with all notebooks, they are wrong.   There is enough drain to other parts to avoid this problem.   I just think it was a technical compromise.   But, in all honest, I feel sorry for those guys (and gals) who have field calls about this problem and go through the usual diagnostics when the problem is not solvable at their end.  

By the way, I have been assured that replacing the motherboard will ameliorate the buzzing.  And, if you look at other posts in different areas, you will find many users with the same problem;  many of whom have changed the mother-of-all-boards and still have the same problem.  One girl purchased over 5 mics and still had the same problem!

 

And, another by-the-way, I sent the tech support an email asking them if they ever look at their own community forum on their own website.  I am still waiting for an answer to that one. 

 

Best rgrds to all posters and keep in posting about this problem since it is not going to go away any more than the Earth is going to get knocked out of its orlbit in the next 3 years.
