Public bug reported:

When listening to audio (pandora internet radio, youtube, etc.), I get a
repeated popping/crackling sound.  When I look at the sound settings
while this is happening, I see "Headphone Output" rapidly appearing and
then disappearing in the "Play Sound Through" section.  The appearance
and disappearance of "Headphone Output" coincides with the popping and
crackling of the sound.

I am wondering if it has anything to do with the fact that my Nvidia
card has a built-in HDMI card that might be interfering with my onboard
sound:

$ cat /proc/asound/cards
 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xf7220000 irq 54
 1 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xf7080000 irq 55
cat /proc/asound/modules
 0 snd_hda_intel
 1 snd_hda_intel

Obviously blacklisting "snd_hda_intel" in /etc/modprobe.d/blacklist.conf
won't work, because it then disables all sound (both onboard and nvidia
are listed as snd_hda_intel).
