    The keyboard volume buttons only offered 100% or 0% volume control.
I uncommented two lines in the file:
/etc/pulse/daemon.conf

enable-lfe-remixing = yes
lfe-crossover-freq = 250

then I enabled "Analog Surround 2.1 Output + Analog Stereo Input" in the Configuration tab of the utility "pavucontrol" (not installed by default).
