I have been using ubuntu 20.04 recently and have a HP pavillion laptop with B&O speakers. However i am not able to hear any sound. though, Bluetooth is working fine.
I have tried many solutions such as :
*sudo apt purge timidity-daemon
*sudo alsa force-reload
*sudo apt install pavucontrol and running pavucontrol.
None of the solutions have worked for me yet.
EDIT: Later I assumed it to be a kernel bug and say a solution using the following commands:
sudo add-apt-repository ppa:kaihengfeng/fix-lp1869819
sudo apt-get update
after that i have tried reinstalling pulseaudio. And now bluetooth devices just after getting connected are automatically disconnected, do not play any sound either.

When experiencing sound issues on your Ubuntu machine, you first need to is check out your headphones and speakers for connection problems. It could be that a audio cable is connected to the wrong port or not connected at all. If you're using a Bluetooth device, check to see if it's paired correctly.
The Temporary fix I found(Worked for me and all my friends).
Suspend your system then start again. Now the sound will work.

What worked for me immediately after all was
pulseaudio --start
sudo apt-get install pavucontrol
from https://www.maketecheasier.com/fix-no-sound-issue-ubuntu/
with no changes to the files in /etc/modprobe.d/
