I have installed Ubuntu Server 11.04 as a Virtual Box VM, which emulates the ICH AC97 audio controller.
mpg321 reports 'No default libao driver available'
According to this page the driver for this device can be loaded at boot time by modifying 'loader.conf', but I cannot find any such file on the system
Is the file called something else, or is it something that I need to create from scratch?
Alternatively is there another way I can get the audio drivers installed?
I am getting the same problem with version 10 Server, and also on a non VM machine with the same audio driver
sudo apt-get install alsa-oss
Add the user to the audio group
sudo adduser username audio
Log out and log in again
Finally run alsamixer and make sure that the master and PCM controls are not muted
