Subject: [PATCH] hdmi - fix surround41 channel mapping
Date: Tue, 21 Sep 2010 14:44:51 +0800 [thread overview]
Message-ID: <20100921064451.GA24445@localhost> (raw)
From: Jerry Zhou <jerry.zhou@intel.com>
Channel 2 and channel 3 were all wrongly mapped to HDMI slot 4.
This shows up as a bug that one channel is "lost" when playing in
surround41 mode.
