<pre>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
<a class="bz_bug_link
bz_status_NEW "
title="NEW - 4k 60hz unavailable RX 560 over HDMI"
href="show_bug.cgi?id=111412">bug #111412</a>) this is the modeline I am using:
Modeline "3840x2160" 594 3840 4016 4104 4400 2160 2168 2178 2250 +hsync
