I'm running ArchLinux with the latest PulseAudio and Alsa from git. I have a
Nvidia GTX550ti card with HDMI output. I would like to be about to output HDMI
audio to my Samsung TV. Right now, I'm having trouble getting any audio output
over HDMI using PulseAudio.

The hdmi audio is on device hw1,7. Currently I have a file
/etc/modprobe.d/sound.conf with the following:

options snd-hda-intel probe_mask=-1,0x2

I have been able to get HDMI output to the TV working through ALSA using
speaker-test and VLC. I have been able to get audio through PulseAudio for
about 1 second by turning the configuration profile on and off for the HDA
Nvidia device in pavucontrol. But after one second or so, the sound cuts out. I
attached the pulseaudio log output and the output of pactl list sinks.

I have tried adding the "load-module module-alsa-sink device=hw:1,7" line to
/etc/pulse/default.pa, but it didn't help. 

Thanks.
