ALSA: hda - Set Stream Type in Stream Format according to AES0
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. Signed-off-by: Anssi Hannula <anssi.hannula@iki.fi> Signed-off-by: Takashi Iwai <tiwai@suse.de>
