That said
So, i think the issue is with the pulseaudio-equalizers, any thing like pulseeffects or pulseaudio-equalizer-ladspa would cause this type of cracking.
That wording makes it sound like you haven't tried either option, based on the assumption that whatever's affecting your current equalizer must affect them all. Which I'd say is a quite short sighted approach for various reasons. First of all, there is no THE pulseaudio-equalizer, they all (like alsaequal) can use different LADSPA plugins with differing implementations. The standard pulseaudio-equalizer equalizer is known for being a bit clunky, that doesn't have to hold true for anything else. FWIW I usually do not use any effects like these, but I've dabbled with pulseeffects and you get vastly more control over the exact processing steps.

By the way I am using pulseaudio in timer based scheduling, so i don't think
buffer_size and fragment_size
would have any difference. I tried with
tsched=0
and it doesn't make any difference. So, i think the issue is with the pulseaudio-equalizers, any thing like pulseeffects or pulseaudio-equalizer-ladspa would cause this type of cracking.
