Bug ID: 60687 Summary: Using radeon.audio=1 blocks hdmi display output on Radeon 5760 Product: Drivers Version: 2.5 Kernel Version: 3.10, 3.11-rc3 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: hasenfrasz.gabor@gmail.com Regression: No
Created attachment 107088 --> https://bugzilla.kernel.org/attachment.cgi?id=107088&action=edit dmesg log for drm and radeon lines
On kernel 3.9 using radeon.audio=1 can produce display and audio on HDMI output. Using 3.10 and 3.11-rc3 with this parameter breaks HDMI output (no screen). Without this parameter HDMI display works fine, but no audio.

I'd like to see output of command avivotool regs hdmi when using 3.9 with audio=1 and then using 3.10/3.11 with audio=1.

drm/radeon/evergreen: setup HDMI before enabling it
Closed source driver fglrx seems to enable infoframes and audio packets at the end, which makes sense, do the same.

--- Comment #10 from Rafał Miłecki zajec5@gmail.com --- (Please make it *after* connecting HDMI display, after it breaks)
https://bugzilla.kernel.org/show_bug.cgi?id=60687
--- Comment #11 from Gabor Hasenfrasz hasenfrasz.gabor@gmail.com --- @Rafał: It's working. After switching to mirroring, or to HDMI only, and entering this command, the display starts working with sound.
