The mono profile is usually thrown away as most hardware does not support opening it in one-channel mode only.
You can configure pulseaudio to do what you suggest by modifying /usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf and /usr/share/pulseaudio/alsa-mixer/profile-sets/extra-hdmi.conf In both files, go to the [Mapping analog-mono] section and change channel-map = mono to channel-map = mono,mono This will take effect the next time pulseaudio is restarted (e g by rebooting). The *major* question is however, whether we should do this by default, and if we risk regressing other hardware by doing so. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/942780 Title: Can't force audio output to be mono (if deaf in one ear) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/942780/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
