The thing is sometimes when I'm watching videos on youtube or wherever firefox has a delay in audio followed by static noise.This applies to firefox only, if I play a movie or something it works properly. Rebooting the system fixes the problem but still it gets annoying. And also while the firefox is open sometimes I can hear a tiny bit of noise coming from the speakers like someone is hitting a table with a finger, a little (tup) every now and then. I'm curious if anyone has similar experience and ultimately a fix for this. I did try to reinstall complete audio but still it makes no difference.

I have the same problems on both of my Ubuntu 20.04 machines, so you are not alone.. so far the only thing that has helped me a little is tinkering with PulseAudio Volume control.. (I particularly had static audio noise when changing output to HDMI, PulseAudio fixed that for me, and I have a constant gentle background clicking when volume is high on my desktop, through headphone speakers, from when I upgraded to 20.04..)
This worked for me:
Go to about:config in Firefox and search for "media.webspeech.synth.enabled" and set it to "false" (double clicking on the entry should do it) then close Firefox. Don't forget to restart Firefox.
