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).
