I created a video of the "Sound Settings" GUI window to show what I'm experiencing. When the audio "pops", my Sound Settings twitches/spasms between headphone and analog output. See here:

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).
