I installed Android on Virtualbox, I'm using Android x86 downloaded from <http://www.android-x86.org/download> I chose version 2.3 the eeepc version (android-x86-2.3-RC1-eeepc.iso).

The problem is the sound is not working, I tried all 3 choices in Virtualbox settings.
My current settings:

```
Host driver: Windows DirectSound
Controller: ICH AC97

```

The choices I tried for the audio controller setting:

```
Intel HD Audio
ICH AC97
SoundBlaster 16

```

I'm currently running Windows 7 and my audio driver is the default windows driver.

I searched and found people with the same issue, but I couldn't understand anything as I'm not an advanced Linux user some solutions talk about the ALSA driver but I couldn't find how to install it and use it.

Also could it be from the installation .iso file I chose ? my computer is `Acer Travelmate 2480`.

**Update**
While checking the Android x86 website I found that we should [use SoundBlaster 16 instead of ICH AC97](http://www.android-x86.org/documents/virtualboxhowto).

I also tried the `alsa_ctl init` command inside the terminal (ALT + F1), and I got this:

```
Unkown hardware: "Dummy" ""Dummy Mixer" "" "" ""
Hardware is initialized using a guess method

```

I checked the version it's 1.0.23
