Debian testing as Guest in Virtualbox gets no Sound
 

I installed Debian testing onto Virtual box on my windows 7 machine using business card CD. Everything seems to work just fine but I am getting no sound. Sound driver appears to be installed and alsa is being loaded on boot up (Get an error if I switch virtual boxes sound card so I know it sees it on the one I am using). Using the intel HD audio card. How can I get the sound to work in my virtual box?

Run alsamixer and check if your sound is muted.

I have already run alsamixer and the sound is not muted.

Are you in the audio group?

Yes my user is in the audio group.

I have tried different install methods of Debian in Virtual Box. The stable Live CD has sound but the Test version of Debian installed from Business Card CD (Net type Install) has no sound. Is there a way to copy the sound settings from a working Debian system on the same computers Virtual Box?

Maybe and that's a big maybe. Try running ' alsactl init ' first then check the mixer again.

This seemed to fix it how strange. Looks like I have to type that in after each reboot. Is there a way to add that to the start up?

Put it in /etc/rc.local

That did absolutely nothing for me. The problem seems to only exist in the Debian Testing branch. Doesn't happen in Stable or Unstable branch. I have decided to use the unstable branch then as it still gives me Gnome 3 but with out the problems found in testing.

before boot up I prefer, on linux host to set sound as

alsa audio driver.....others include oss etc

hardware set as ....ac97.....others are intel and sb16
