Audio output through HDMI works with pulseaudio but not Jack, and jack works with onboard analog sound. Debian testing (buster) with jack configured through cadence. Nvidia binary drivers installed through Debian repos (384.111). I'm a little confused why the jack log says alsa is using an Intel driver.

Did you ever find a solution for this?

I'm encountering exactly the same problem: HDMI audio works with PulseAudio but not with Jack. Onboard analog sound output works with both. I've tested through all the subdevices listed on my machine: hw:NVidia, hw:NVidia,3, hw:NVidia,7, hw:NVidia,8, hw:NVidia,9, hw:NVidia,10.

In alsamixer, make sure SPDIF isn't muted. It always starts as "muted" for me, and that's the HDMI audio out.
