I have recently got a new laptop Teclast F5 which has a few recurring issues with Ubuntu.
I am currently using Ubuntu Budgie 19.10 but I was having the same issues with Kubuntu 19.10.
When I boot the system and shutdown I get loud clicks/pops from the speaker is there a solution to this problem.
Unfortunately, this is a common problem found in linux modules enabling support for various audio hardware. The most sensible thing to do in this case is writing a bug report. The exact same issue has been fixed a short while ago for most creative based sound cards.
[note: you need to be root for this].
Open file in console using: sudo nano /etc/modprobe.d/alsa-base.conf [or, use Dolphin, open with Kate.]
Add the following line at the bottom of the page:
options snd-hda-intel power_save=0 power_save_controller=N
save and reboot.
