I'm not sure on the sound issue, but I remember having the same exact
issue when I was setting up my current system. From what I can recall,
it involved changing some setting in the xorg configuration.
Specifically adding the Driver line (as below).

# /etc/X11/xorg.conf.d/10-display.conf:
Section "Device"
	Identifier "Intel Graphics"
	Driver "intel"
	Option "AccelMethod" "UXA"
EndSection

Try adding this file (not sure if the UXA line was necessary), restart
X, and see if it fixes the issue with xbacklight.
