"dummy output" sound driver
Posted: 31. Dec 2010, 19:34
I started a new Ubuntu project with a hardware emergency, and I had to build a new Ubuntu platform in VirtualBox on my daughter's netbook (Win7 32bit).
The sound just plugged and played - I never even had to look at its settings.
Then I got a new notebook (Lenovo Win7 64-bit), and I exported the Ubuntu as an appliance and imported it.
Now the sound driver (in the Mixer popup) is "Dummy Output", and it doesn't make sound.
Version numbers & /etc/ cats available on request!
