    ALSA: hda - Revert stream assignment order for Intel controllers · cd50065b
    Takashi Iwai authored
    We got a regression report for 3.15.x kernels, and this turned out to
    be triggered by the fix for stream assignment order.  On reporter's
    machine with Intel controller (8086:1e20) + VIA VT1802 codec, the
    first playback slot can't work with speaker outputs.
    
    But the original commit was actually a fix for AMD controllers where
    no proper GCAP value is returned, we shouldn't revert the whole
    commit.  Instead, in this patch, a new flag is introduced to determine
    the stream assignment order, and follow the old behavior for Intel
    controllers.
