            Bug ID: 98809
           Summary: No sound over DisplayPort with Radeon R9 380 and
                    amdgpu
           Product: xorg
           Version: unspecified
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/AMDgpu
          Assignee: xorg-driver-ati at lists.x.org
          Reporter: matthias.h.nagel at gmail.com

Sound over DisplayPort with Radeon R9 380 and amdgpu does not work. The device
is listed by lspci, the driver "snd_hda_intel" is loaded and the card is
detected by ALSA. ALSA lists six possible devices but none of them works.

No matter what device configuration I select in PulseAudio/Phonon (HDMI 0
through HDMI 5) my monitor stays silent. If I try to by-bass PulseAudio and
directly try to play an audio file with aplay I get the same negative result.
