--- Comment #1 from Florent Le Coz <louiz at louiz.org> ---
The issue is still present on kernel 4.0.7.

Little precision, that may be useful to diagnose the problem:

- If I boot with that HDMI-connected screen turned off and then I turn it on
with my X session already fully started, it is not automatically detected (the
screen says “no signal”), but this used to work on older versions of linux
(can’t remember which one introduced this “regression”).
Next, if I manually configure it with that command:

xrandr --output DVI-0 --mode 1920x1080 --output DVI-1 --right-of DVI-0 --mode
1920x1080 --output HDMI-0 --right-of DVI-1 --mode 1920x1080

the image on the screen works, but not the sound.

- However, if I boot while that screen is already turned on (or if I turn it on
while still on the gdm login screen), it is automatically detected and both the
image AND the sound BOTH work immediately.
