Two audio issues on Mojave

[kartagis]

I've got the below issues on Mojave. I'm putting them in one issue because I think they might be related. Here they are:

1. When I turn on my computer, I get a hissing & crackling sound from internal speakers.
2. I can't get any sound from speakers. It's like the rear jack or the front jack are not working. Speakers work though.

What can I do about these?
