Even after fixing that, I can't play audio on Venice2:

root@localhost:~# speaker-test -Dhw:0,3 -c 2

speaker-test 1.0.27.1

Playback device is hw:0,3
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 16384
Period size range from 32 to 8192

Thanks for checking Stephen.  I'll fix the reset name.

This is the state of the tree I used when I tested on Venice2 just now:
* ae57dbf - (HEAD) ARM: tegra: venice2 - Enable HDA (2 minutes ago)
* 6224524 - ARM: tegra: Add Tegra124 HDA support (2 minutes ago)
* 468ca57 - ALSA: hda - Add driver for Tegra SoC HDA (2 minutes ago)
* 928099e - ALSA: hda/hdmi - Add Nvidia Tegra124 HDMI support (2 minutes ago)
* 701eac4 - clk: tegra124: Enable hda to hdmi clocks (3 minutes ago)

Ah, I was missing that clock patch. Hopefully Peter will pick it up for
the Tegra clock tree soon.

Now I have the same results as Thierry; speaker-test looks like it
should be working, yet I don't hear any audio from the monitor. I know
the monitor works, since I've used it extensively for testing GeForce
GPU HDMI audio.

Probably a silly question: Is it un-muted?
amixer -c0 cset name='IEC958 Playback Switch' on

Yes (well I used alsamixer interactively, but it's the same thing, I
believe)
