New Dell Inspiron Laptop - Microphone failing

We tried reaching you on a private message but did not receive a response. Please feel free to reply to the private message whenever you are available.

We are having the same issue, except we purchased 250 of these and ita happening to almost all of them

You're not alone as apparently lots of us have this problem. Short term fix is to change the driver from Realtek to the generic Microsoft HD Audio Device in Device Manager. The long term fix is going to take Dell+ Realtek+Microsoft to recognise the problem and fix the drivers.  

Same here. My office bought 3 Inspiron 17 3000 (Model 3793) and all of us are having the same issue. We've spent considerable time on the phone troubleshooting with Dell. Updated all software, drivers, etc. per their recommendations. Dell is now telling us that the hardware and software are all working correctly, so it must be Zoom, but we have replicated the issue in Microsoft Teams and Google Meet, so that cannot be true. Really hoping they start to take it seriously and create a fix.

My Inspiron 3793 has no "boost" slider.  I called Dell support in November about the failing mic and the technician was able, from his end, to access a slider and boost my levels.  That lasted 2 months but the problem is back and, having NO BOOST SLIDER on my computer I again called support and went through 1.5 hours of watching the tech check the obvious without luck - he does not know how the 1st tech fixed the mic.  So what to do???

My laptop: Inspiron 13 5378 2-in-1 

I am having the same problem, the microphone stops working after 10mins of videocall. Have tested with different microphones, no success. Tried to use troubleshooting for sound, done diagnostics on Dell`s website, and follow tutorials to check what was the problem, but none solved it. This really needs to be addressed ASAP. Would Dell be able to contact me regarding this?

Please send me a private message about how to fix this, as you did for the first user. My Dell laptop is 2 weeks old and I cannot use the microphone on Zoom. The sound works, the drivers are up to date. But the microphone tests at 2% and Zoom cannot pick up sound. 

My Wifes new Inspiron 3000 has the same issue, short work around is to use a external usb camera with microphone. Has worked without issues

Dells issue appear to be related to their DAC conversion.. If you go into the driver and advanced settings and change the conversion rate to 16 bit 8000 hz the issue becomes a lot less, works on zoom for more time. maybe a new driver or bios update wood fix it

i purchased my new laptop less than one month ago. I have the same problem since last week. please help me. i live in France not in USA.
