--- Comment #1 from Jürgen Scholz juergen.scholz.84@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.
