From 108dc8e8b44a4c64ac53676cc05f6234340ccd4a Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Mon, 14 Oct 2013 13:17:50 -0400 Subject: [PATCH] drm/radeon: rework audio option MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In 3.12 I changed audio to be enabled by default, but you still had to turn it on via xrandr. This was confusing to users so change it to minic the previous behavior: - audio option is set to -1 (auto) by default which is the current 3.12 behavior (audio is enabled but requires xrandr to turn it on). - if audio = 1, the audio is enabled without needing to mess with xrandr (previous behavior) - audio = 0 disables audio It retains the new feature of allowing the user to enable audio on the fly with xrandr, but turns audio on automatically if radeon.audio=1 is set which is what most users expect.
