    ALSA: hda - Increment default stream numbers for AMD HDMI controllers · 7546abfb
    Takashi Iwai authored
    It turned out that some AMD HDMI controllers still don't provide
    proper values in GCAP register (all zero), and the driver assigns only
    one stream in that case, although the connected codec chip supports
    more than one stream.
    
    In this patch, the default max number of streams for AMD HDMI
    controllers is increased to 8, which  should suffice for most use
    cases.  The overhead by this increase is more azx_dev struct and BDL
    allocations, so it's negligible.  Of course, if the controller
    provides a proper GCAP register, the register value would be used.
