ok, I am not sure I understand why there are
In practice, NVIDIA GPUs only support sending video signals over at most
two of these connectors at once, and hence the HD audio controller only
allows two audio streams to be configured at once. The exact set used can
be dynamically reconfigured by changing xorg.conf or using NVIDIA's tools
Recent NVIDIA GPUs include an audio controller that hosts a number of
different ALSA PCM objects. For example, consider the following output
from aplay -L:
hdmi:CARD=NVidia_1,DEV=0
HDA NVidia, NVIDIA HDMI
HDMI Audio Output
hdmi:CARD=NVidia_1,DEV=1
HDA NVidia, NVIDIA HDMI
HDMI
If I hack /usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf to
change hdmi-stereo's device-strings value to e.g. hdmi:%f,0, hdmi:%f,1,
etc., then I can cause pulseaudio to open whichever subdevice I wish. This
proves to me that this is simply an enumeration issue and nothing more
