From: Libin Yang <libin.yang@xxxxxxxxxxxxxxx> 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 sound/pci/hda/patch_hdmi.c | 374 ++++++++++++++++++++++++++++++++++++++++++--- 1 file changed, 351 insertions(+), 23 deletions(-) -- 1.9.1 _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
