      ALSA: hda - rename function not_share_unassigned_cvt() · 300016b9
      Mengdong Lin 提交于
      The function name not_share_unassigned_cvt() is opposite to what it does.
      This patch renames it to intel_not_share_assigned_cvt(), and addes comments
      to explain why some Intel display codecs need this workaround.

      ALSA: hda - hdmi: Disallow unsupported 2ch remapping on NVIDIA codecs · 611885bc
      Anssi Hannula 提交于
      NVIDIA HDMI codecs do not seem to follow the Audio Sample Packet (ASP)
      channel mapping (as set by verb F32h per HDA specification 7.3.3.41)
      when playing back 2-channel audio (CEA CA 0x00).
      
      Basically this means that specifying swapped channels for stereo audio
      (FR,FL) does not take effect, and e.g. this command plays back on the
      wrong channel:
      speaker-test -c2 -Dhdmi:CARD=NVidia,DEV=0 -m FR,FL -s1
      
      Multichannel audio is not affected.
      
      This issue has been confirmed to exist on codec 0x10de0015 by me and on
      0x10de0040 by Juho Teperi.
      
      Disable 2ch FL/FR channel swapping on all NVIDIA HDMI codecs that use
      the standard HDA channel mapping system. Since this is a very minor
      functionality loss, we err on the side of disabling it for newer codecs
      as well until any future testing confirms that this issue has been
      fixed.
