When i turn off the speaker and on again from the above interface the problem gets fixed temporarily for few minutes but then emerges again.

Also when I connect my bluetooth headphones the also do not show up in playback devices although they get connected successfully. they were working fine before this problem started.

here is the output for journalctl --user -xe | grep pulse it shows so many errors. (i am removing repeated lines from the output)

I solved it. It was happening because of configuration of pulse to suspend the sinks on idle.
it was suspending the module for few seconds of inactivity.
commented out the line
load-module module-suspend-on-idle
in /etc/pulse/default.pa and /etc/pulse/system.pa and now it works perfectly fine.
