I'm seeing this bug in Linux Mint 19.1 (Ubuntu 18.04 base). The audio devices do not appear and disappear in the "Sounds" GUI. The workaround I've found is to do this in a terminal:
pulseaudio -k && sleep 5 ; pulseaudio -D Sometimes this works for hours, and sometimes it works for minutes, after killing/restarting the PulseAudio daemon, as above. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1353013 Title: Popping/Crackling sound when playing audio in Ubuntu 14.04 Status in nvidia-hdmi-pulseaudio package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: 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).
