[pulseaudio] no audio output over HDMI (nvidia 210)

I have an nvidia 210 using HDMI to an HDTV.  The video works perfectly but I have no audio with pulse.  Audio does work with alsa ONLY with the following in ~/.asoundrc:

defaults.pcm.card 0
defaults.pcm.device 7
defaults.ctl.card 0

I can query the nvidia card with aplay:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 7: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 8: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 9: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

When I try using aplay to test which of these (3,7,8, or 9) to use I get no sound output:

$ for i in 3 7 8 9; do aplay -D plughw:0,$i /usr/share/sounds/alsa/Front_Center.wav; done
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

I also get no sound output with mplayer either, although, it appears to be playing just fine.

$ mplayer -ao pulse 01-Remnants.ogg

I think you need to specify a probe_mask for snd-hda-intel in /etc/modprobe.d/alsa.conf
