    I've been using Parallels pro for almost a year now, and among all virtualization solutions, it's probably the gold standard. But what I absolutely can't understand is why Parallels has such horrendous audio performance. I'm running the ARM version of Windows 11 on the latest Parallels 20. After just 10-15 minutes of using Windows 11, audio playback starts stuttering and breaking up. It makes using Windows 11 as a full-fledged system practically impossible -- I can't listen to music, watch movies, or join audio conferences because the sound starts to lag as if I'm on a Pentium I. And yet I have two powerful machines -- one with an M4 Pro and another with an M3 Pro -- and the problem occurs identically on both.

    I've tried disabling the hypervisor, adjusting allocated RAM and CPU cores, increasing Parallels' priority -- but none of that makes a meaningful difference. Is no one else experiencing this? I've seen forum posts dating back to 2021 mentioning the same issue. Has anyone found a fix? I've tried using Foobar and MusicBee - in every case, the audio starts stuttering after a short time. Meanwhile, audio playback on native macOS is flawless. But in that case, why even use Parallels?
