you have to specify CONFIG_SND_DYNAMIC_MINORS=y when building the driver


[    4.637413] ALSA hda_codec.c:4506 Too many HDMI devices
[    4.637414] ALSA hda_codec.c:4508 Consider building the kernel with
CONFIG_SND_DYNAMIC_MINORS=y
[    4.637644] ALSA control.c:352 control 0:0:0:HDMI/DP Jack:0 is already
present
[    4.639220] hda_codec: cannot build controls for #0 (error -16)
