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: freedesk...@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
