I have a Lenovo P50 which contains an NVIDIA Quadro M2000M in =
reverse PRIME
configuration: The HDMI port is connected to the NVidia card.  While gettin=
g an
image onto the HDMI port works just fine, there is no audio.

I asked about this on IRC, the logs are at

hlight_names=3D&date=3D2017-11-24#t-2034>.
 The summary is that I tried running the following script (after stopping X=
):

rmmod nouveau
setpci -s 01:00.0 0x488.l=3D0x2000000:0x2000000

echo 1 > /sys/bus/pci/rescan
modprobe nouveau

But that did not help.  I then started X again, and lspci still shows only
