From ea87d1c493aba9cf3f645eae0d6d9c0fd44d3189 Mon Sep 17 00:00:00 2001 From: Anssi Hannula Date: Tue, 3 Aug 2010 13:28:58 +0300 Subject: ALSA: hda - Add support for HDMI HBR passthrough Passing IEC 61937 encapsulated compressed audio at bitrates over 6.144 Mbps (i.e. more than a single 2-channel 16-bit 192kHz IEC 60958 link) over HDMI requires the use of HBR Audio Stream Packets instead of Audio Sample Packets. Enable HBR mode when the stream has 8 channels and the Non-PCM bit is set. If the audio converter is not connected to any HBR-capable pins, return -EINVAL in prepare().
