Date: Tue, 24 Apr 2018 15:26:08 +0000 [thread overview]
Message-ID: <bug-199493-2300@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=199493
Bug ID: 199493
Summary: no audio over HDMI with amdgpu.dc=1 (on R9 380X)
Product: Drivers
Version: 2.5
Kernel Version: 4.17.0-rc2
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: haro41@gmx.de
Regression: No
Audio over HDMI doesn't work (no sound), if dc is enabled (amdgpu.dc=1).
Hardware is R9 380X (Tonga), i use ALSA only.
With dc disabled (amdgpu.dc=0), audio basically works, but i get 'noisy' sound
usually.
The only way to get correct audio over HDMI is currently:
disable dc (amdgpu.dc=0) and start windows once, then warm boot to linux.
It looks like: the windows driver is initializing the hardware correctly, while
amdgpu doesn't.
