I'm on Kali Linux 2.0, on a laptop in dual boot with Windows 7 and I recently installed some module(chiptune) music players and after a reboot the next day the only sound card that I found in sound settings is Dummy Output.So I tried purging pulseaudio and alsa and then installing them back again but it didn't work so here's a few commands that may give you more info :$ lspci -v00:03.0 Audio

could have been the cause of this.I don't know if it's useful but this is the result of modprobe command for the intel driver:$ sudo modinfo snd-hda-intel filename:
