My bluetooth earphones were working fine with ubuntu 20. Yesterday i ran the $ dconf reset -f /org/gnome/ command to reset all themes to defualt's . Afterwards ubuntu is able to connect to my bluetooth earphones but not able to output any sound.
I tried all answers in Ubuntu 20.04 no sound out of Bluetooth headphones. However the issue seems to something else.
I noticed that pavucontrol was not able to connect to pulseaudio
$ sudo pavucontrol Pavucontrol is stuck in loading screen
However only pavucontrol will launch it successfully. Pavucontrol successfully launched Typing pulseaudio will give this error.
sankethbk7777@sankethbk7777-Lenovo-ideapad-330-15IKB:~$ pulseaudio
E: [pulseaudio] pid.c: Daemon already running.
E: [pulseaudio] main.c: pa_pid_file_create() failed.
I have included the output of { sudo lshw | grep product | head -n1 && sudo lspci -knn | grep Net -A3 && lsusb -v; } >output.txt 2>&1 here https://pastebin.com/wWGCDEPt
