Felipe:

Is it a particular kind of audio (such as playing from a software music 
synthesizer), or is it all audio (including from an audio player)?

I think you said it always happens, whether the audio is played through 
the laptop speakers, or external speakers (or earphones).

If the volume is turned too high, you can get a 'crackling' sound 
because of over-modulation, but you've probably already tried turning 
the volume down.  Going from 16.04 to 18.04 could have ended up with the 
volume set higher.  Some things allow you to go beyond the 100% volume, 
which could cause that.

If the problem is only with the sound played on external speakers, there 
are things that can trip you up there, that would not affect the laptop 
speakers.

I have a lot of experience with software music synthesizers on Linux, 
and if the problem is limited to that, I'm pretty sure I can help you.
