Do I need to reinstall the operating system?

[Jimbonatius]

I'm having an issue where when I wake my macbook up, the sound or videos won't work until a restart occur. It's been happening to me for a bit and it's a bit annoying. I'm wondering if there's something wrong with the sleep mechanism. Like I literally can't play local videos or stream anything. The only fix is a restart. Is there a setting I need to disable or...

Would really appreciate some help.

Raise a support ticket by Apple Chat. I did that for my wake problem - screen would be darkened or black on wake. Still not resolved.
