Prev: [PATCH 0/2] ALSA: hda - support HDMI HBR passthrough
Next: tc6387xb: add __devinit/__devexit annotation for tc6387xb_probe/tc6387xb_remove
From: Anssi Hannula on 3 Aug 2010 06:40 Set bit 15 (Stream Type) of HDA Stream Format to 1 (Non-PCM) when IEC958 channel status bit 1 (AES0 & 0x02) is set to 1 (non-audio). This is a prequisite for HDMI HBR passthrough.
