I am a total newbie in Ubuntu. To try it, I installed Sun xVM VirtualBox 1.6.0 on my Windows XP SP2 host. I then installed Ubuntu 8.04 on the virtual machine in VirtualBox. With a lot of help, I successfully installed Ubuntu. The network access is also working and I can browse the internet through the Ubuntu guest. The only problem I am facing is configuration of my sound card. I use vlc media player. It plays the audio files I have but no sound comes from the speakers. Infact, no sound at all when I am in Ubuntu. I searched for tips on configuration (similar to graphics card configuration to get various screen resolution modes) but to no avail.
Can anyone help me in configuring my sound card (Realtek AC97 Audio as seen from Windows XP host)?
