Not good news:  Good 'eld#3.0',  No HDMI sound

I'd like you to take a little time to review my procedure, correct it if
necessary, and thus keep us in sync.

cd /root/linux                                  # Linus directory
make mrproper
git checkout 8e9e3d2deacc460fbb8a4691140318f6e85e6891
# At this point, files to be patched are each copied ('cp -p') to <name>-orig.
cd /root/Temp                                   # Patch directory
cp -p ../linux/drivers/gpu/drm/nouveau/core/engine/disp/hdanva3.c-orig
hdanva3.c
cp -p ../linux/drivers/gpu/drm/nouveau/core/engine/disp/hdminva3.c-orig
hdminva3.c
cp -p ../linux/drivers/gpu/drm/nouveau/core/engine/disp/hdminv84.c-orig
hdminv84.c
#
patch -Np8 -i hdmi-1.patch ; echo $?
patch -Np8 -i hdminva3.patch ; echo $?
patch -Np8 -i hdminva3-3.patch ; echo $?
cp -p {hdanva3,hdminva3,hdminv84}.c                  
/root/linux/drivers/gpu/drm/nouveau/core/engine/disp/
# Build, reboot, test:
cat /proc/asound/card1/eld#3.0                  # Good, Bad?
aplay -D plughw:1,9 test.wav                    # HDMI sound?
