Comment 1 Dieter Nützel 2015-02-26 20:15:09 UTC

It is a regression: 3.19 to 4.0-rc1
Seems to be duplicate of https://bugs.freedesktop.org/show_bug.cgi?id=89327
When you hit DRI/DRM/gfx bug please have a look first at bugs.freedesktop.org

Try to reenable HDMI audio with:

xrandr --output HDMI-0 --set audio on
or
xrandr --output HDMI-0 --set audio auto
