如果VMWare player啟動linux時出現：
這個可能是使用"瑞昱高傳真音效"卡，設定上的問題，
我把"音效裝置連接設定"，改成"AC97前置面板"(原本是HD Audio前置面板)
就可以在VMWare Player下的Fedora 20聽到聲音了。
或者參考以下的改法：

If you have RealTek speakers, look
within the RealTek HD Audio Manager. Select the yellow folder near the
analog panel, and make sure "Disable front panel jack detection" is
selected. This fixed the problem for me.
Apparently RealTeks detection blocks the linux virtual machine from accessing the resource, and causes the error.
