Analog Output blinks or resets with pop or stutter

CentOS 7 x86_64 Asus P8Z68-V motherboard Realtek ALC892 Gnome 3 desktop nVidia GTX 770 with nVidia's driver
I have 3 devices I can choose from in Gnome's Sound Setting applet:
HDMI / DisplayPort2 - GK104 HDMI Audio Controller Digital Output (S/PDIF) - Built-in Audio Analog Output - Built-in Audio
I use Analog Output and sound is heard through the external speakers.
The volume icon on the top of the Gnome desktop blinks randomly and the sound skips at the same moment. I've updated to the latest mainline kernel but the issue still persists. It's like the application momentarily switches output devices. When the disconnect/reconnect occurs, the blue selection bar that highlights which device you want to use for sound output "blinks" and a 4th output device is momentarily shown/removed. The 4th device is "Headphones - Built-in Audio"
I've searched for a fix and the most promising leads didn't work:
options snd_hda_intel powersave=0 position_fix=1 or 2
I've tried disabling auto-muting in alsamixer... no luck
This card works flawlessly in Gnome 3 under archlinux, ubuntu, as well as Windows 7. Something about CentOS?
