Tessa, I think these two things might be related...
1. Pop!OS doesn't like pulseaudio: UnreportableReason: This is not an official Pop!_OS package. Please remove any third party package and try again. 2. You have two sound servers and should only have one: Pulseaudio: Installed - Yes (/usr/bin/pulseaudio) Running - Yes Jack: Installed - Yes (/usr/bin/jackd) Running - No It sounds like System76's Pop!OS ships with jackd and they don't want you using pulseaudio. Certainly having both installed I would expect one of them might fail to access the sound hardware. This also means I am not sure the correct way to fix this other than it sounds like pulseaudio shouldn't be installed at all in Pop!OS. Suggested quick fix: Uninstall either your jackd packages, OR your pulseaudio packages. Fully clean fix: Reinstall Ubuntu from scratch, downloading it from here: http://releases.ubuntu.com/18.10/ ** Changed in: pulseaudio (Ubuntu) Status: Incomplete => Opinion -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1799007 Title: [System76 Oryx Pro] no sound after 18.10 upgrade Status in pulseaudio package in Ubuntu: Opinion Bug description: After upgrading to 18.10, the sound in my System76 Oryx Pro no longer works, it no longer shows any of the audio output devices, not even the builtin HDMI which usually always shows. Not sure what happened, but this is a major regression and needs to be fixed. Note that this isn't the same as the bug with Timidity taking exclusive soundcard access (https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1797714) as I don't have any timidity packages installed. --- ProblemType: Bug ApportVersion: 2.20.10-0ubuntu13 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: tessa 11703 F.... pulseaudio /dev/snd/controlC0: tessa 11703 F.... pulseaudio /dev/snd/pcmC0D0c: tessa 11703 F...m pulseaudio /dev/snd/pcmC0D0p: tessa 11703 F...m pulseaudio CurrentDesktop: pop:GNOME DistroRelease: Pop!_OS 18.10 InstallationDate: Installed on 2018-03-05 (230 days ago) InstallationMedia: Ubuntu 17.10 "Artful Aardvark" - Release amd64 (20180105.1) NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair nvidia_modeset nvidia Package: pulseaudio 1:12.2-0ubuntu4 [origin: Ubuntu] PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 4.18.0-10.11-generic 4.18.12 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: Daemon not responding.
