So I'm on Win 10, in a corporate environment. My PC is a beast, internet is fast as it can be, but a few times a week the Spotify Desktop app and most browsers will start having stuttering, maybe every 10 seconds, or sometimes less frequent, but enough to be noticable and ruin the listening experience.
There isn't any clear indication as to the cause, and nothing makes it go away. The only way I can listen without any stuttering is to use the Microsoft Edge browser, but that player randomly stops outputting any audio so I'm constantly fighting the buggy web player instead. I can stream from other services without any sound quality issues.
