When a sound starts playing, no sound is heard until I change the volume
either from the volume control panel or from the media keys. This
happens in internet videos, spotify, games etc. When I stop a sound,
after a few seconds, I hear a sound like something is shut down. After
that I need to repeat this to hear sound. If I play sound before hearing
the shut down sound, it plays correctly.
I could not find any logs or clues what is causing this. I am not sure
whether this is related with pulseaudio or alsa.
