-Subject: [PATCH] [aml] Multichannel-PCM and HD Audio passthrough
-
-1. If we want passthrough, is should be redirected to device 1. To make sure device 1 output is enabled, set device 0 to stereo.
-2. Set digital_codec parameter to notify sound driver about audio format.
-3. Amlogic wants 48kHz for EAC3 passthrough.
-4. Identify Amlogic audio output as HDMI.
