no sound in kali, sound through headphones works, already installed alsa and pulseaudio

[r0tati0n]

I found something:

I booted windows (multiboot), unmuted the speakers and played sound. Speakers worked.
Then I rebooted to kali and suddenly sound was working on the normal speakers, before it was certainly not muted.

Why was the unmuting in windows carried over to kali?

I don't now, it must be a problem specific to your laptop's audio card.
