[Desktop-packages] [Bug 1717992] Re: Sound silently plays to "Dummy Output"
my workaround is running `pulseaudio -k` and restarting Spotify. Chrome doesn't need a restart to play. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1717992 Title: Sound silently plays to "Dummy Output" Status in linux package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: Since upgrade to 4.10.0-35-generic in Ubuntu 17.04, the sound card is detected, but pavucontrol has only "Dummy Output". Bar animation shows audio is playing, but no sound is heard. alsamixer is working fine, but audio still can't be heard.
