ALSA: hda - Set Stream Type in Stream Format according to AES0
Anssi Hannula [Tue, 3 Aug 2010 10:28:57 +0000 (13:28 +0300)]
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.
