It turns out that after following the below guide, I found that another package called timidity is conflicting with PulseAudio and causing it to fail detecting my audio devices.
So I uninstalled it and PulseAudio is now working fine.

sudo apt-get remove timidity

https://wiki.archlinux.org/title/PulseAudio/Troubleshooting#The_only_device_shown_is_%22dummy_output%22_or_newly_connected_cards_are_not_detected

I ran this command:
HP-Pavilion-dv6-Notebook-PC:~$ sudo fuser -v /dev/snd/*
                     USER PID ACCESS COMMAND
/dev/snd/controlC0: timidity 852 F.... timidity

/dev/snd/pcmC0D0p: timidity 852 F...m timidity
/dev/snd/seq: timidity 852 F.... timidity
