    ALSA: hda - Add support for HDMI HBR passthrough · ea87d1c4
    Anssi Hannula authored
    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().
