[N550JV, Realtek ALC668, Speaker, Internal] fails after a while

[erenyilmaz]

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.
