Gnome, proprietary nvidia driver, pulseaudio, no hdmi sound

Hi I definitely used to have working hdmi sound on my NVIDIA Gtx 970 with proprietary driver. Kernel 5.12.8-arch1-1

I wrote the following script in my home dir and added it to /usr/lib/udev/rules.d/61-gdm.rules

DRIVER=="nvidia", RUN+="sh /home/andrew/audio.sh"

cat audio.sh                                                                               
setpci -s 01:00.0 0x488.l=0x2000000:0x2000000
rmmod nvidia-drm nvidia-modeset nvidia
echo 1 > /sys/bus/pci/devices/0000:01:00.0/remove
echo 1 > /sys/bus/pci/devices/0000:00:01.0/rescan
modprobe nvidia-drm

I also tried switching back from pipewire-pulse to pulseaudio but it didn't seem to make a difference. Also tried running pulseaudio -k.
