Hi everyone,
I'm a long time Lubuntu user and I have been facing audio issues from
a `dist-upgrade` from 16.04 to 18.04. I have detailed the question
there:

The audio is stuttering/crackling whenever played in external
speakers/headphone or the laptop's speaker.
@Felipe:
Unfortunately I can't help you, because I know nothing about "sound"
in linux. But, you have made a detailed post, however, the machine
you are trying to get sound in . . . doesn't seem to be mentioned
here?? I didn't click on any links . . . .
We do have a few people who do know about "sound" here and perhaps
they will reply to your question??
The only suggestion I would try is that since Lu is under heavy
development, it might behoove you to move forward to 19.04?? I'm
running 19.10 development and overall it is "good" . . . but I did
have some "dependency" issues with an nvidia driver that broke the GUI
recently, so I wouldn't say to jump up to that, but 19.04 is very good
and **might** address or fix your issues??

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.
