            Bug ID: 60687
           Summary: Using radeon.audio=1 blocks hdmi display output on
                    Radeon 5760
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.10, 3.11-rc3
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: hasenfrasz.gabor@gmail.com
        Regression: No

Created attachment 107088
  --> https://bugzilla.kernel.org/attachment.cgi?id=107088&action=edit
dmesg log for drm and radeon lines

On kernel 3.9 using radeon.audio=1 can produce display and audio on HDMI
output. Using 3.10 and 3.11-rc3 with this parameter breaks HDMI output (no
screen). Without this parameter HDMI display works fine, but no audio.

Do you have some second monitor or other machine to ssh the first one?

I'd like to see output of command
avivotool regs hdmi
when using 3.9 with audio=1 and then using 3.10/3.11 with audio=1.

    drm/radeon/evergreen: setup HDMI before enabling it

    Closed source driver fglrx seems to enable infoframes and audio packets
    at the end, which makes sense, do the same.

@Rafał: It's working. After switching to mirroring, or to HDMI only, and
entering this command, the display starts working with sound.
