Thanks. In that case it sounds like maybe Wine was accessing the sound devices directly. If an app does that then PulseAudio is unable to access the sound hardware at the same time.
The solution is to get all apps to change to using PulseAudio instead of ALSA, so they can all share the sound hardware. ** Changed in: pulseaudio (Ubuntu) Status: New => Invalid -- 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/1832610 Title: [Dell Inspiron 5480] No sound at all from internal speakers Status in pulseaudio package in Ubuntu: Invalid Bug description: No sounds at internal speakers but headphones works ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: pulseaudio 1:11.1-1ubuntu7.2 ProcVersionSignature: Ubuntu 4.15.0-1039.44-oem 4.15.18 Uname: Linux 4.15.0-1039-oem x86_64 ApportVersion: 2.20.9-0ubuntu7.6 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: marcelo 10930 F.... pulseaudio CurrentDesktop: ubuntu:GNOME Date: Wed Jun 12 13:00:36 2019 InstallationDate: Installed on 2019-06-03 (8 days ago) InstallationMedia: Ubuntu 18.04 "Bionic" - Build amd64 LIVE Binary 20180608-09:38 SourcePackage: pulseaudio Symptom: audio Symptom_AlsaPlaybackTest: ALSA playback test through plughw:PCH successful Symptom_Card: Áudio interno - HDA Intel PCH Symptom_DevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: gdm 1813 F.... pulseaudio marcelo 10930 F.... pulseaudio Symptom_PulsePlaybackTest: PulseAudio playback test failed Symptom_Type: No sound at all Title: [HDA-Intel - HDA Intel PCH, playback] No sound at all UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 03/24/2019 dmi.bios.vendor: Dell Inc. dmi.bios.version: 2.2.0 dmi.board.name: 07G539 dmi.board.vendor: Dell Inc. dmi.board.version: A01 dmi.chassis.type: 10 dmi.chassis.vendor: Dell Inc. dmi.modalias: dmi:bvnDellInc.:bvr2.2.0:bd03/24/2019:svnDellInc.:pnInspiron5480:pvr:rvnDellInc.:rn07G539:rvrA01:cvnDellInc.:ct10:cvr: dmi.product.family: Inspiron dmi.product.name: Inspiron 5480 dmi.sys.vendor: Dell Inc.
