When I'm playing sound in my guest OS's (Windows 10, High Sierra and Mojave) it works great while I'm in the guest OS environment, but when I use the host OS the audio stutters (small gaps and distortions) when I'm opening applications, opening new tabs in Safari and other things. I run Parallels Desktop Version 15.1.0 (47107) with the latest Parallels Tools installed. My guest OS's all run on 2 processors and have 8192MB memory assigned. My host OS is Mac OS Catalina 10.15 (19A583) on a MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports, 2,3 GHz Dual-Core Intel Core i5, 16 GB RAM). Hope there is a way to fix this.
