ok, I am not sure I understand why there are several devices in the
firs

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 Aud
