Thanks for the bug report. Since pulseaudio is unchanged (the same version) in 19.04 from 18.10 I think we can exclude that as a possible cause.

1. The first idea I have about possible causes is a kernel change (and the kernel has changed a lot). Please try some older kernels from here:

  https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D

(for reference, Ubuntu 18.10 uses kernel 4.18).

2. Also, is the crackling from internal speakers or headphones?

3. Finally, please check that something hasn't accidentally enabled:

  Settings > Sound > Over-Amplification

  as that could cause crackling.
