Thanks Daniel for the suggestion, I'll try it. The audio issue doesnt always happen and I can't spot exactly what the triggers are, this morning 3 sessions are all working fine.
any suggestion for what to do if it occurs again? 'kill all pulseaudio' doesnt help, neither does asking it to restart. I wonder if the bug is actually elsewhere, as the other issue i see is when plugging in a usb drive - another session will try to mount it, but fail to get access permission and a window pops up asking for admin login/pwd. that happens in the background session, the front session just shows a window saying failed to mount. Coincidence? Ive seen that bug before with ubuntu and mint going back to distros built on 16.04LTS, but still see it on occasion today. -- 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/1814964 Title: No audio when logging in as second user. Only dummy audio device seen Status in pulseaudio package in Ubuntu: New Bug description: Laptop with multiple user accounts. Logging in as any user has working audio, but if that session is locked and a second user logs in, the second user gets no sound. Workaround is for both users to log out and 2nd user to log in a fresh session. Obviously a problem if you cant log in as the first user. No sound hardware is shown in the MATE sound preferences, output pane only shows "dummy output". Looking at 'top' or system monitor shows that 1st user pulseaudio is running, but 2nd user pulseaudio is sleeping. $ lspci -nnk | grep -A2 Audio 00:1b.0 Audio device [0403]: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio [8086:3b57] (rev 05) Subsystem: Dell 5 Series/3400 Series Chipset High Definition Audio [1028:0410] Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: pulseaudio 1:11.1-1ubuntu7.1 ProcVersionSignature: Ubuntu 4.15.0-45.48-generic 4.15.18 Uname: Linux 4.15.0-45-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/by-path', '/dev/snd/hwC0D3', '/dev/snd/hwC0D0', '/dev/snd/pcmC0D7p', '/dev/snd/pcmC0D3p', '/dev/snd/pcmC0D0c', '/dev/snd/pcmC0D0p', '/dev/snd/controlC0', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: CurrentDesktop: MATE Date: Wed Feb 6 21:19:25 2019 InstallationDate: Installed on 2018-11-12 (86 days ago) InstallationMedia: Ubuntu-MATE 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) SourcePackage: pulseaudio Symptom: audio Symptom_Card: HDA-Intel - HDA Intel Symptom_Jack: Speaker, Internal Title: [Latitude E4310, IDT 92HD81B1X5, Speaker, Internal] Pulseaudio fails to detect card UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 05/12/2017 dmi.bios.vendor: Dell Inc. dmi.bios.version: A15 dmi.board.name: 0T6M8G dmi.board.vendor: Dell Inc. dmi.board.version: A00 dmi.chassis.type: 9 dmi.chassis.vendor: Dell Inc. dmi.modalias: dmi:bvnDellInc.:bvrA15:bd05/12/2017:svnDellInc.:pnLatitudeE4310:pvr0001:rvnDellInc.:rn0T6M8G:rvrA00:cvnDellInc.:ct9:cvr: dmi.product.name: Latitude E4310 dmi.product.version: 0001 dmi.sys.vendor: Dell Inc.
