Comment 50 for bug 1321421

I had the same problem with an Asus Z97-Pro motherboard running 14.04 with Gnome.
As instructed, I added the line <options snd-hda-intel vid=8086 pid=8ca0 snoop=0 >
to the bottom of the file < /etc/modprobe.d/alsa-base.conf > and the sound problem went away.
Thanks very much for resolving this.
