OK, if "realtime-scheduling = no" didn't work then at least we still know that you have:
Pulseaudio: Installed - Yes (/usr/bin/pulseaudio) Running - No <--- most likely crashed so next please: 1. Look in /var/crash for crash files and if found run: ubuntu-bug YOURFILE.crash Then tell us the ID of the newly-created bug. 2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us. 3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1. Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1810861 Title: USB type C audio adapter (from a Pixel 3) doesn't produce any sound Status in linux package in Ubuntu: Incomplete Status in pulseaudio package in Ubuntu: Incomplete Bug description: I use a logitech z200 that works fine, i use it with a usb type c adapter that came with my pixel 3, my speakers arent shown at all in the settings or make sound, its not the usb c adapter because it works fine on my windows dual boot and has worked at one point on ubuntu, regardless of the fact that ubuntu has never recognized my thunderbolt port, i use ubuntu 18.10 by the way when i use lsusb, one of the results is google inc., which is my headphone adapter, i can tell because when i unplug it it goes away, even when i plug it into the 3.5 mm headphone jack it doesn't work, i don't know if im forgetting something or not, this is the second time im typing this because i accidentally closed the first tab of this, whats interesting, is now that i go to alsamixer, and press f6 i see option 1.Headphone Adapter, i select it and set the volume all the way up and go to something that makes audio and nothing happens, then i unplug it and see if it disappears, surely enough it does --- ProblemType: Bug ApportVersion: 2.20.10-0ubuntu13.1 Architecture: amd64 AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/by-id', '/dev/snd/controlC2', '/dev/snd/pcmC2D0c', '/dev/snd/pcmC2D0p', '/dev/snd/by-path', '/dev/snd/controlC1', '/dev/snd/hwC1D0', '/dev/snd/pcmC1D2c', '/dev/snd/pcmC1D0c', '/dev/snd/pcmC1D0p', '/dev/snd/controlC0', '/dev/snd/hwC0D0', '/dev/snd/pcmC0D11p', '/dev/snd/pcmC0D10p', '/dev/snd/pcmC0D9p', '/dev/snd/pcmC0D8p', '/dev/snd/pcmC0D7p', '/dev/snd/pcmC0D3p', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: DistroRelease: Ubuntu 18.10 InstallationDate: Installed on 2018-10-21 (78 days ago) InstallationMedia: Ubuntu 18.10 "Cosmic Cuttlefish" - Release amd64 (20181017.3) IwConfig: lo no wireless extensions. enp37s0 no wireless extensions.
