The patches are trying to support dynamically binding PCM to pin in HDMI/DP audio.
The pin will not bind to any PCM if there is not monitor connected. When there is a monitor connected to the port (pin), driver will try to find a proper PCM to assign to the port and setup the pin if necessary.
Libin Yang (5): ALSA: hda - hdmi begin to support dynamic PCM assignment ALSA: hda - hdmi playback without monitor in dynamic pcm bind mode ALSA: hda - hdmi operate spdif based on pcm ALSA: hda - hdmi dynamically bind PCM to pin when monitor hotplug ALSA: hda - hdmi setup pin when monitor hotplug in pcm dynamic assignment mode
