Subject: Revert "drm/radeon: only mark audio as connected if the monitor supports it (v3)" causes pink line on Epson projector
Date: Thu, 23 Jul 2015 15:09:27 +0200	[thread overview]
Message-ID: <55B0E787.6000805@redhat.com> (raw)

Hi Alex,

I believe that the revert of "drm/radeon: only mark audio as connected
if the monitor supports it (v3)" causes issues with some projectors
which used to work before, see:

https://bugzilla.redhat.com/show_bug.cgi?id=1236337

The user reports that going from 4.0.5 to 4.0.3 fixes this, and 4.0.5
is the release where the revert landed. I've inspected the EDID of
the projector and drm_detect_monitor_audio() should return false
for it.

Adding radeon.audio=0 to the kernel cmdline fixes the pink line.

Regards,

Hans
