      ALSA: hda/hdmi - allow PIN_OUT to be dynamically enabled · 75fae117
      Stephen Warren 提交于
      Commit 384a48d7 "ALSA: hda: HDMI: Support codecs with fewer cvts
      than pins" dynamically enabled each pin widget's PIN_OUT only when the
      pin was actively in use. This was required on certain NVIDIA CODECs for
      correct operation. Specifically, if multiple pin widgets each had their
      mux input select the same audio converter widget and each pin widget had
      PIN_OUT enabled, then only one of the pin widgets would actually receive
      the audio, and often not the one the user wanted!
      
      However, this apparently broke some Intel systems, and commit
      6169b673 "ALSA: hda - Always turn on pins for HDMI/DP" reverted the
      dynamic setting of PIN_OUT. This in turn broke the afore-mentioned NVIDIA
      CODECs.
      
      This change supports either dynamic or static handling of PIN_OUT,
      selected by a flag set up during CODEC initialization. This flag is
      enabled for all recent NVIDIA GPUs.
