    ALSA: hda - Disable 64bit address for Creative HDA controllers · cd21931f

    commit cadd16ea upstream.
    
    We've had many reports that some Creative sound cards with CA0132
    don't work well.  Some reported that it starts working after reloading
    the module, while some reported it starts working when a 32bit kernel
    is used.  All these facts seem implying that the chip fails to
    communicate when the buffer is located in 64bit address.
    
    This patch addresses these issues by just adding AZX_DCAPS_NO_64BIT
    flag to the corresponding PCI entries.  I casually had a chance to
    test an SB Recon3D board, and indeed this seems helping.
    
    Although this hasn't been tested on all Creative devices, it's safer
    to assume that this restriction applies to the rest of them, too.  So
    the flag is applied to all Creative entries.
