Parallels Workstation virtualizes the Realtek AC'97 compatible sound card. 

Device status:

Enable option allows/prohibits using the sound device in the virtual machine. If the sound 

device is enabled, it can be connected/disconnected while the VM is running. However if 
you wish to temporarily disable operations with a sound device without deleting it from 
configuration, deselect the Enabled check box.  

Note: If you start the operating system with the sound device disabled, you cannot change 
this option when the virtual machine is running.  

ƒ  To start the guest OS with the sound device activated, select the Activate sound at startup 

check box.

eComStation guest OSes. You can install it instead of standard one.
