Windows 10: What is making my mic output a high pitched, fast chipmunk audio?

I occasionally try using an app (Cortana, audio recording from the mic, etc) that uses the mic, and find the don't work because the audio is converted to a high pitched, fast chipmunk sound. It hasn't happened often enough for me to figure out what is doing it and repeat it. It's just intermittent.

I didn't have this problem before going from Windows 8.1 to Windows 10, and it still happens after the anniversary update.

It's easy to fix by disabling and then enabling the mic in device properties window, but I just want it to work without having to do that.

Mic not working right after Win 10 Anniversary Update

Since the update, whenever I reboot, the mic though active, does not detect any sound, or the sound comes through the system as a high pitched chipmunk sound. Disabling and re-enabling the mic fixes it until the next reboot.

I've reinstalled the Logitech driver and tired the generic driver. It doesn't make a difference.

Anyone have a fix for this?

 

Microsoft lifechat lx 3000 and windows 10

hello! I haven't been able to resolve this but my mic is now giving me a constant high pitched buzzing noise. I can't fix it no matter what!

 

The problem has gotten worse. Now, when I boot up, the mic, though active, will not work at all unless I disable it then reenable it.

 

Update - The "chipmunk" sound was corrected by lowering the sampling rate of the webcam mic from 48 Khz to 16 Khz. Why did it work before the update at the higher sampling rate?

The problem of the mic showing up as "This device is working", and enabled, but not detecting any sound unless disabled/re-enabled went away for a couple of days. Now it's back after a restart yesterday, and a boot up this morning. Requires cycling the enabled status again.
