The attached file AudioDevicesInUse.txt suggests that 'audacity' is stealing the hardware device from pulseaudio -- bypassing it.
If that is the issue then it's unfortunately not a bug. You need to be sure that all audio software (including audacity) is configured to use PulseAudio only, and not ALSA directly. Because the latter will prevent all other audio (via PulseAudio) from working. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1828136 Title: [Intel DH67CL, Realtek ALC892, Grey SPDIF Out, Rear] No sound at all Status in alsa-driver package in Ubuntu: Incomplete Bug description: After rebooting I have no sound.
