It appears this is a known issue since 2016 where there was an SDL patch
that broke the audio in pcsx2.   

https://bugzilla.libsdl.org/show_bug.cgi?id=3228

As per the above, the SDL team did not fix the bug because the fix would
have required a change in the API functionality.   

As such, the PCSX2 team addressed the issue themselves and pushed a fix
out to the development branch

https://github.com/PCSX2/pcsx2/issues/1095

Note the comment here saying it's fixed in PCSX2 Git

https://github.com/PCSX2/pcsx2/issues/1402


I compiled PCSX2 1.5.0-dev and it fixed the issue without any changes to
SDL.

Just adding this in because PCSX2 was very much unusable with
crackling/popping audio when using ALSA+Pulseaudio (recommended)
settings.
