According to Rodrigo Rivas:
Have you tried running "alsamixer -D hw" and see if there are any muted
channels in your hardware?
Master is at 87% normally. Once GDM runs, it zeros out and mutes. Also, once pulseaudio starts, the Master channel zeros out and mutes.
Also, once I had a similar problem and solved it by simply deleting the files at ~/.pulse/*.tdb
Unfortunately this is also not working. I even tried deleting the entire ~/.pulse directory with no luck. Thanks for the help. ~Kyle
One last idea. Maybe the gnome-settings-daemon is playing dumb with your sound. I think you can disable the sound plugin of g-s-d using dconf (org.gnome.settings-daemon.plugins.sound.active). I don't know if that will affect also to the GDM greeter, but it is worth trying it. As a last resort you could also try renaming "/usr/lib/gnome-settings-daemon-3.0/libsound.so" and see what happens. -- Rodrigo
