Once my computer is boot and when I try to play youtube video or play sound files such as mp3, I can click on the play button but the media would not play. This gets resolve only after when I select different audio profile in Pulseaudio controller. This problem is on going for me for months and I would finally like to solve it somehow. It happened on my system that has USB sound card (audio interface), and I recently noticed that the same thing is happening for my laptop as well (just built-in internal sound card). So, I am suspecting that this problem is related to Pulseaudio updates at some point in time because I did not have this issue couple months back.

Where should I look first to solve this issue?

Thanks.

Make sure you don't have conflicting sound servers running first and foremost

systemctl --user status pipewire{,-pulse} wireplumber pulseaudio

needs to either show wireplumber or pulseaudio existing, if they are both running then you'll have a logical conflict between which service tries to handle the incoming request, in which case you should lean towards preferring pipewire-pulse instead of pulseaudio, because the former is much more actively maintained.

If that isn't it, what output do you get from

sudo fuser -v /dev/snd/*
pactl list cards
pactl list sinks
pactl list sink-inputs

before and after the fix
