Hi, I have been testing today to try to reproduce this. I have number of duplicates which give roughly the same error, they are all slightly different hence why I have not marked as duplicate but I suspect that a singular fix 'should' resolve them all.
Could you please try something ? Please modify /usr/share/pulseaudio/alsa-mixer/paths/analog-input.conf comment out "required = volume" from the [Element Capture] section. You can comment out with '#'. Then restart and see if the bug is still present. thanks, Conor ** Visibility changed to: Public ** Changed in: gnome-control-center (Ubuntu) Status: New => In Progress ** Changed in: gnome-control-center (Ubuntu) Assignee: (unassigned) => Conor Curran (cjcurran) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/977620 Title: Testing Sound through mbox2 after testing sound through analog output[soundnua]: gnome-control-center crashed with SIGSEGV in vfprintf() Status in “gnome-control-center” package in Ubuntu: In Progress Bug description: Trying to get mbox to to work., tested sound through analog output.
