Description Sebastián Lacuesta 2019-09-28 00:14:26 UTC

When I connect a fullhd monitor over display port and a 4k tv over hdmi at 60Hz, then sound is like accelerated on monitor and completely absent on tv. Using my soundcard, sound it's good.
Hdmi cable is 2.0. Videocard is Radeon 7. I'm using amdgpu kernel module.

Well, just updated drivers in Windows, used sound from TV. Then reboot on Linux and problem solved. I have rebooted several times on Linux before doing this and problem persisted. Now it looks everything fine.
