Windows virtual sowed music pop-up solution in Parallels desktop

Recently, a friend of the PC6 Apple Network made use of Macbookpro, there are Macbookair, with PD9 and pd10,win7,win10 have the problem of pop. Small series on the Internet a search encountered this problem of friends also many, seemingly did not find a particularly good way. I tried, I feel PD with a soft sound card, encounter system resource occupation will encounter a burst sound, my virtual machine is the main MAC settings, left Windows resources, plus win10 than Win7 occupy system resources (CPU), so win10 than Win7 burst sound more. I have verified this here.

Workaround:

Set up the virtual machine, in hardware, sound, from the default value to build in Output

The blasting sound is solved, but it takes a long time to verify.

Attach the description of PD:

Use the output list to select the necessary devices. You can select one of the following devices:

Default: Select this option if you want to use an output device that is set as the default in Mac OS.

Built-in output. Select this option if you want to use an outgoing device from your Mac.
