--- Comment #1 from Jürgen Scholz <juergen.scholz.84 at gmail.com> ---
I am trying to use a displayport connection between a Tahiti XT R9 280X and my
monitor to output audio.

The initial report seems still valid: Using HDMI for audio works with the same
monitor and it does not with displayport.

Running aplay -D plughw:0,$i does not lead to audible sound. No error messages
though.

Trying to force audio on with xrandr --output DisplayPort-0 --set audio on does
not work either.
