            Bug ID: 111416
           Summary: 4k 60hz on RX 560 over HDMI = no sound
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: freedesktop@azelphur.com

Hi,

If I switch to 4k 60hz on my RX 560, sound instantly drops out.

I can enable/disable sound by running
`xrandr --output HDMI-A-0 --mode 3840x2160 -r 30`
`xrandr --output HDMI-A-0 --mode 3840x2160 -r 60`

No messages appear in dmesg or Xorg log when switching between 30/60hz. So I'm
not sure what information to provide with aiding debugging. Please let me know!

I'm using a custom modeline since 4k 60hz option is unavailable by default (see
bug #111412) this is the modeline I am using:

Modeline     "3840x2160" 594  3840 4016 4104 4400  2160 2168 2178 2250 +hsync
+vsync
