--- Comment #13 from François Jacques francois.jacques@gmail.com --- Created attachment 139083 --> https://bugs.freedesktop.org/attachment.cgi?id=139083&action=edit REAL dmesg output (with debug messages)
Last attachment for tonight. This one its not /var/log/messages but really dmesg output. We can see the debug messages as I disconnected the HDMI cable, then connected the DP cable (no image, audio enabled), then disconnected and reconnected the HDMI cable.
Hopefully that will be useful to stabilize DP display with audio.
Interesting bits: [ 1288.208351] [drm:radeon_process_aux_ch.constprop.2 [radeon]] dp_aux_ch flags not zero [ 1288.208354] [drm:drm_dp_dpcd_access] Too many retries, giving up. First error: -5
