A few weeks ago, I built a new PC for myself and have since been using it for both work and leisure. I run a dual-boot on it of Fedora 29 and Windows 10.
When I set up Fedora, I decided to try something different and went for the XFCE spin. It worked well, but due to a somewhat complex monitor setup (two screens and a TV that I want to use sometimes as a third monitor) where each screen needs to have separate scaling/DPI, I resorted back to using Gnome on Wayland so that I can control the scale of each monitor individually. This might have been possible on XFCE, but mucking around with
xrandr seemed more annoying than it was worth.
However when I installed Gnome, I noticed something: Previously, going to settings -> sound would allow you to raise the global system volume over 100%. Now it wasn’t letting me.
I don’t know if this is because I installed Gnome later (and thus didn’t get some default that is set on the “normal” Fedora Workstation ISO) or if the lack of this ability happened as a result of newer Gnome than I had used in the past.
In any case, I did some searching around and source code hunting discovered there’s a handy little
gsettings toggle that can be flipped to re-allow that behavior.
[rick@sapphire ~]$ gsettings list-keys org.gnome.desktop.sound input-feedback-sounds theme-name allow-volume-above-100-percent event-sounds
[rick@sapphire ~]$ gsettings get org.gnome.desktop.sound allow-volume-above-100-percent false
[rick@sapphire ~]$ gsettings set org.gnome.desktop.sound allow-volume-above-100-percent true [rick@sapphire ~]$ gsettings get org.gnome.desktop.sound allow-volume-above-100-percent true
And by the time I had flipped back to the Settings window, the audio boost was there again and I could slide it over beyond 100%.
Hope this helps someone.
