Go to: Tools > Android > AVD Manager
Press the "edit" (pencil) icon next to your AVD
Change "Graphics" to "Software".

I'm having this issue in Visual Studio / Windows. Any way to access AVD manager? – Shimmy Weitzhandler Oct 29 '18 at 05:00

It's not working with me. First, Android Studio 3.2.1 Tools doesn't have "Android" in the dropdown. It DOES have "AVD Manager". But when I edit, I can't change "Graphics" to "Software". Option is set to "Automatic" and is GREYED OUT. – DSlomer64 Apr 25 '19 at 10:05

@DSlomer64 The reason it's grayed out is because the virtual device has playstore enabled on it. Try creating another virtual device with out playstore support and you will be able to select a value. – Hitesh Bisht May 26 '19 at 09:29
@HiteshBisht `creating another virtual device with out playstore support` and how does one do that? – likejudo Jun 12 '19 at 02:32
@likejudo That is very simple. When you click on "Create virtual devices" a window opens where you can select from some device from list. In that table of list there is a column called "Play Store" that denotes if playstore is there or not in the device. You can also see playstore icon in the row for "Pixel 2" and "Pixel" device. So you just have to either select another device or create one yourself and it will not have playstore installed in it. – Hitesh Bisht Jun 17 '19 at 10:47

This seemed to work, but only while Windows 10 thought it had a microphone plugged in. After unplugging, the bad behaviour returned. – MZB Oct 24 '19 at 22:36

Go to Sdk -> emulator -> lib and then open configuration settings named hardware properties, find the hw.AudioInput field and set default to no:

One option, following @palehorse's terse clue, is to edit your AVD's config.ini to disable audio.

Android Studio > Tools > AVD manager ...
Against your (previously setup) Virtual Device > Actions > Down arrow [Click it] > Show on Disk ...
This will take you to a directory like C:\Users\<username>\.android\avd\my_API_29_-_Android_10.avd
In that directory edit config.ini
Replace ...
```
hw.audioInput=yes
```
... with ...
```
hw.audioInput=no
hw.audioOutput=no
```
An entry for hw.audioOutput did not previously exist.
Restart the emulator a few times to get rid of lingering error messages.

See Android AVD set custom hardware for other ways to disable audio.

I found using a bluetooth microphone also removes the problem. But temporarily. Restarting the emulator without my bluetooth microphone connected produces the problem again. I did not try a corded microphone. – John Bentley Aug 28 '20 at 07:44

Old question I know, but I was able to resolve this by editing the emulator and disabling the hw.audioInput setting.

It's your new Windows 10 Update.

To Fix: Click Start, go to ⚙ Settings> Privacy Settings> Microphone. Turn On "Allow apps to access your microphone"

In Window 10. I was able to fix it by doing...

go to C:\Users<YOUR_USER_NAME>.android\avd\Pixel_XL_API_30_R_.avd
open config file
find hw.dPad and set yes like hw.dPad = yes
Restart your AVD
