Audio not working on Android running on Virtualbox?

Question

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.

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

Answer 1

Check for your sound cards detected using

alsa_aplay -l

and select the first card

alsa_ctl init 1

Have you checked here of using this

alsa_amixer set PCM 100 unmute

or do as described here

Read some crap to understand about Sound Architecture or Try using VMware Player or VMware Workstation its a better alternative, here you can find some good tutorials
