This is a note to let you know that I have just added a patch titled drm/radeon: fix speaker allocation setup to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt1. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From e55f0fb3aa6997c830beb78194289658f094ed84 Mon Sep 17 00:00:00 2001 From: Alex Deucher <alexander.deucher@amd.com> Date: Mon, 13 Oct 2014 11:51:50 -0400 Subject: drm/radeon: fix speaker allocation setup commit 4910403836ded89803fab201d4b5caaa85de3a89 upstream. If the sad_count is 0, set the hw to stereo and change the error message to a warn. A lot of monitors don't set the speaker allocation block.
