Host USB audio devices may not work as expected in a virtual machine.
Make sure you have the following settings for your virtual machine running on a Windows host: Open Device Manager and expand Universal Serial Bus controllers.
Boot your VM with identical VM setting from an Ubuntu installation ISO with "Try Ubuntu" to exclude a bad install of the audio system on the already installed Ubuntu.Open a guest session on your virtual Ubuntu to make sure is it not a per-user setting that conflicts with the audio system.To debug this let me suggest the following approaches: it will play music on professional sound cards via ASIO, as well supporting.
