kernel 4.15.0-99-generic: no internal sound / no sound through earphones audio jack
kernel 4.15.0-99-generic-revert225, kernel 4.15.0-96-generic, kernel 4.15.0-91-generic : sound works as expected (both internal and through audio jack) [However, if my earphones are plugged in prior to booting, then no sound will come out. I must unplug them (sound will come out through internal speakers), and then plug them back in. Probably a different issue though, as it isn't new.] For all kernels, I hear a brief clicking sound through my earphones when booting and rebooting. I attach alsa-info.txt for kernels 4.15.0-99-generic-revert225, 4.15.0-99-generic and 4.15.0-91-generic ** Attachment added: "alsa-info.txt files for kernels 4.15.0-99-generic-revert225, 4.15.0-99-generic and 4.15.0-91-generic" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1875916/+attachment/5365557/+files/alsa-info.zip -- 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/1875916 Title: upgrading to 4.15.0-99-generic breaks the sound and the trackpad Status in linux package in Ubuntu: Confirmed Bug description: I am using kubuntu LTS 18.04. This morning I was promped to update the kernel to the 4.15.0-99-generic. After the upgrade I did not manage to get any sound. I checked everything, pavucontrol, alsamix, everything was in order, the streams showed as if they were playing, however I couldn't get any sound from the speakers headphones and I could not get any sound recorded either. I then rebooted with the previous version of the Kernel, and have my sound back without doing anything at all. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.14 Architecture: amd64 AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: CurrentDesktop: KDE DistroRelease: Ubuntu 18.04 HibernationDevice: RESUME=UUID=4a7a721a-7a2e-4644-a881-34adcb28e1ba InstallationDate: Installed on 2019-01-29 (455 days ago) InstallationMedia: Kubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) IwConfig: lo no wireless extensions. wlp108s0 no wireless extensions.
