Subject: [PATCH 3.12 17/72] drm/radeon: enable speaker allocation setup on dce3.2

From: Alex Deucher <alexander.deucher@....com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 3803c8e5b50946dd6bc18972d9190757d05648f0 upstream.

Now that we disable audio while setting up the audio
hw, we should be able to set this up without hangs.
