title: No Audio in Android-x86
body: <p>I've setup an <a href="http://www.android-x86.org/" rel="nofollow noreferrer">Android-x86</a> image (4.0-RC1-eeepc) in VirtualBox on a Dell Latitude D820.  This particular ISO is not for the laptop, but of all available ISOs it works the best.</p>
  
  <p>I have worked through some of the troubles I have come across (by not having an ISO for my device), but I haven't been able to get the sound working.  The Android-x86 VirtualBox tutorial and other online resources directed me to use the ALSA driver with SoundBlaster 16, but this has not worked.</p>
  
  <p><a href="https://stackoverflow.com/questions/5894582/alsa-aplay-not-recording-on-android">This</a> question got me to look at some of the ALSA commands to see what I could find, but I'm not getting anywhere with it.</p>
  
  <p>With the ALSA driver and SoundBlaster controller I get the following from <code>alsa_ctl init</code></p>
  
  <pre><code>Unknown hardware: "Dummy" "Dummy Mixer"
  Hardware is initialized using a guess method
  </code></pre>
  
  <p>This looked very wrong to me so switched to the Intel HD Audio as the other question did.</p>
  
  <p>With the ALSA driver and Intel HD Audio controller I get the following from <code>alsa_ctl init</code></p>
  
  <pre><code>Unknown hardware: "HDA-Intel" "SigmaTel ID 7680" ...
  Hardware is initialized using a guess method
  </code></pre>
  
  <p>While this looks a little more promising, I still have no audio.</p>
  
  <p>Since Android is <em>basically</em> Linux, I thought I would be able to translate a Linux solution.  Several webpages have content similar to <a href="http://ubuntuforums.org/showthread.php?t=1475185&amp;page=2" rel="nofollow noreferrer">this one</a> saying to modify <code>/etc/modprobe.d/alsa-base.conf</code> and add <code>options snd-hda-intel model=CORRECT_MODEL</code> and this appears to help a lot of Linux users.  However, this doesn't seem applicable to Android.  At least not to me, since I don't have <code>alsa-base.conf</code></p>
  
  <p>I know so very little about audio and ALSA.  Is there anyting jumping out from what I have above?  Even a nudge in a general direction would be great.</p>
  
  <p>Some questions that I have:
  What does it mean when I get the <code>Unknown hardware: "Dummy"</code> info?  No audio device?</p>
  
  <p>Lastly, I have verified that my sound works outside of virtual box.  My first throught is that since my laptop can run Linux with sound, I should be able to include the Linux drivers in Android.  Does that make any sense?  Unfortunately, I also don't really know how to go about doing that either.</p>
  
  <p>Thank you</p>
