Sound Card Gone, Ubuntu 12.04
I am not sure what changes I made in an attempt to find out why my microphone wasn't working well, but the result of my undocumented changes is that now I have no audio at all on my Dell Vostro 3450 Laptop.
The Sound settings --> Hardware tab, which used to show an audio device, is now empty.
I tried to remove and then re-install packages that had to do with audio (pulse audio, alsa), but to no avail.
How can I get my audio back?
(I posted this question also on the Ubuntu Forums (http://ubuntuforums.org/showthread.php?p=12249713) and so far got no answer, so I am trying my luck here too. Whereever I get a solution first, I'll update the other post.)
ICH AC97 is the only VirtualBox VM audio setting which allows me to get sound when running Ubuntu as a guest and either Windows or OS X (10.6.8) as the host.
In particular, if a VM's audio setting is Intel HD Audio then sound does not work in an Ubuntu 12.04 guest.
On the other hand, sound will only work for a Windows 7 (64-bit) guest when the audio setting is Intel HD Audio. This can be rather annoying when you are working with a VM which dual boots either Ubuntu or Windows 7 as the guest OS.
I have never investigated this further to find out why it works this way or if there is a way to work around it. If you happen to find one, please let us know about it.
Note: You will have to "power off" your VM to change its audio setting.
Thanks for your answer. I am not sure why you thought I was referring to a virtual machine. This is a normal installation. In the meantime I was able to solve the problem, I am not sure exactly how, because I had tried so many things before the problem was fixed, but it was with the help of the following guide:
