Premier por sucks

I only have this kind of problems when in my Preferences > Audio Hardware > Default Input is set to anything other than "No Input".

Without telling us more details, like your particular  CPU, your OS, your RAM, and the media involved, we can't help. And most of us are getting pretty good playback btw.

If your CPU is say a KF, and you've got mostly long-GOP/mp4 media, then ... your CPU doesn't have QuickSync, so it cannot do hardware H.264/5 encode work. That's why we need to know all the details.

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
