我正试图让自己的第一台无法服务器从周四开始工作，并且到目前为止所有工作都很顺利，我很满意。但我需要声音在我的MainVM（游戏VM）和其他VM上运行。我试图通过我的主板声卡，但没有运气，当我使用它时，我得到波涛汹涌的声音。我尝试了我的海盗船vengence 2100耳机，它是usb，几乎没有声音，我的G930耳机（也是USB）也是如此。这是一个已知的问题吗？有工作吗？这是我需要做的最后一件事。
有我的装备设置：
I7 4930k @4.5ghz
32 GB of ram @ 2400 mhz G.SKILL Ripjaws
GPU1:HD4770<- unRAID
GPU2:GTX780<- Gaming VM
HDDs:
Array:
1xWD 4GB I think it's a blue<- NAS shares (some use cache) and windows server 2012
1X 750GB HDD seagate SATAIII
Unassigned:
1XSamsung PRO SSD 512GB<- Gaming VM and an other little VM
