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 Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1832610 Title: [Dell Inspiron 5480] No sound at all from internal speakers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1832610/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
