Android AVD installs custom hardware

I am trying to reduce the ridiculous CPU usage of my Android emulator.

Thanks to this answer, I found out that CPU usage can be significantly reduced by turning off the sound.

Decision

I found out that there are three ways to start the emulator without sound.

Like a command line flag:
```
$ emulator -avd <name> -noaudio 
```
~/.android/<name>.avd/config.ini and replacing this line:
```
 hw.audioInput=yes 
```
with these two:
```
 hw.audioInput=no hw.audioOutput=no 
```
Instead of using the AVD graphical manager, use the following command to create an emulator:
```
 $ android create avd -n <name> -t <target> 
```

Vs

All of these methods have disadvantages.

It is required to pass the -noaudio flag each time. This means that it cannot be started from the AVD manager.
config.ini reset every time editing is done using the AVD manager.
It is required to explicitly set each property of the device instead of just using a pre-configured configuration.

Trying (unsuccessful) solution

I decided that it would help just clone an existing device and mute the sound there.

However, this just created ~/.android/devices.xml , and I could not describe exactly how to turn off the default sound or any ini files containing hardware definitions.
