No sound on Ubuntu Linux: “cannot open mixer: No such file or directory” (solved)

I had trouble getting audio to work on a Ubuntu 15.04 system with Intel chipset audio (Intel Corporation 9 Series Chipset Family HD Audio Controller). Trying to run the ALSA mixer would look like this:

$ alsamixer
cannot open mixer: No such file or directory

The fix was to edit /etc/modprobe.d/alsa-base.conf at the very end of the file (changes bold):

# Keep snd-usb-audio from beeing loaded as first soundcard
options snd-usb-audio index=0
options snd-hda-intel index=-2

I modified the index value for the snd-usb-audio module to zero and added a line for the snd-hda-intel module. Afterwards the mixer would start as expected.
