    ALSA: hda - enable HDMI audio pin out at module loading time · 606c0cee
    Wu Fengguang authored
    We found that enabling/disabling HDMI audio pin out at stream start/stop
    time will kill the leading 500ms or so sound samples. Avoid this by enabling
    pin out once and for ever at module loading time.
    
    The leading ~500ms audio samples will still be lost when switching from
    X-channel playback to Y-channel playback where X != Y. However there's no
    much we can do about it: the audio infoframe has to change and it looks like
    either G45 or YAMAHA requires some time to switch the configuration.
