Internal mic picking up during recording from USB

I’ve recently started using Audacity to record some old records onto Windows 10 laptop. Sometimes the pcs internal mic is activated, other times not. I tried disabling the internal mic from the device manager with no change. I stumbled upon a “randomly occurring” device driver labeled as a “Microphone Array (3-USB PnP Audio Device)”. It seems when this device driver is not shown, the internal microphone is active, even though I have the Realtek High Def Audo driver disabled. At one point when the Microphone Array was showing, I disabled that driver and my recording seems to be working fine.

Where does the “array” driver come from and go to? Why isn’t it always showing? Is it started up by Audacity? If so, why not all the time? I haven’t discovered any pattern to when it comes up and when it doesn’t.

Any help forwarded to xxx@xxx would be appreciated.

No-one will be emailing you solutions so I removed your email address. It’s dangerous to post one on the forum anyway. We’re a SPAM magnet.

It’s also a forum, not a Help Desk. Users helping each other.

This needs to wait for a Windows elf.


Audacity supplied by us does not add audio drivers to Windows Sound. USB PnP audio devices appear if you connect such a device to the USB port of your computer.

Please tell us your Audacity version (all three numbers, see the pink panel at the top of the page) and tell us exactly how you are connecting the turntable to the computer. Give us all the necessary makes and model numbers. Are you connecting a USB turntable to the computer using a USB cable? Or is it a standard turntable and you are connecting a USB phnoo amplifier between the turntable and the computer? If so, that turntable or pre-amplifier is probably the USB Pnp device (Windows will call it a “microphone” even if it isn’t).

You must see the USB turntable or pre-amplifier in the Recording tab of Windows Sound before you open Audacity, and you must select that USB device as recording device in Audacity’s Device Toolbar.

If that USB turntable or pre-amplifier device comes and goes, check the USB cable is tight both ends, and try a different cable.

If you need more help, disconnect all USB audio devices except the one that is for the turntable, then open up Help > Audio Device Info… top right of Audacity, save that to a file using the OK or Save button and attach the file here. Please see here for how to attach files:
