I installed Fedora 18 Xfce Spin as a guest operating system on VirtualBox.It has no sound.
The operating system settings are:
Host Driver:Windows DirectSound
How can I solve this problem?
I found my question's answer Here. Problem is not about virtualbox audio settings on guest operating system.The settings should be like I made.xfce-mixer was not installed.After I had installed the problem gone.
Perhaps that post helps another searcher.
