Re: MCP78 no HDMI audio

First let's make things clear ;-)
I manage to make hdmi audio work. This happened at 1:30 a.m., with 
my avreceiver booming kde opening session sound at thunderstorm-like 
volume for the happines of my neighbours XD

I didn't pay enough attention to you user classification, but if you want to 
place me somewhere I tell what I did, I post here some history because it 
will be useful to others

2.6.29.1 kernel isn't supported by many software in stable release I need 
(i.e. Lirc). This is, in my opinion, why gentoo still marked 2.6.27 as latest 
stable.

-First thing I did is compiling 2.6.27 kernel with its alsa version. Analog 
audio was detected, hdmi was not.

-I recompiled kernel without alsa, and built externally alsa 1.0.19. I 
wrongly used the old alsa utils, so HDMI were not recognized by alsaconf.

-i switched to 2.6.29.1 (which ships alsa 1.0.18a)  and upgraded alsa 
utils to 1.0.19. Hdmi was detected by alsaconf, but still didn't play 
anything from virtual console. I also found out lirc could not compile. I 
decided to ask help on this list, and meanwhile concentrate on lirc and 
mythtv.

-i came back to 2.6.27, used alsa 1.0.19 with new alsa utils. Hdmi were 
recognized. Installed lirc, kde, mythtv and other good software.

-i booted for some reason to 2.6.29.1 and when kde started BOOM!

Hdmi works on 2.6.29.1 with alsa 1.0.18a.
Hdmi DOESN'T work on 2.6.27 with alsa 1.0.19.
I suspect (can't bet anyway) nvidia driver for X unlocks hdmi audio on my 
mother board. This because in bios settings under HDMI audio I only have 
"Disabled" and "AUTO" (there is no "Enabled"  -_- )

This is my WORKING setup:

marco@minibox ~ $ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.18a.

marco@minibox ~ $ uname -r
2.6.29.1

marco@minibox ~ $ cat /etc/asound.conf
pcm.!default hdmi:NVidia
pcm.iec958 hdmi:NVidia

marco@minibox ~ $ aplay -L
hdmi:CARD=NVidia
    HDA NVidia, NVIDIA HDMI
    HDMI Audio Output
null
    Discard all samples (playback) or generate zero samples (capture)

marco@minibox ~ $ ls /proc/asound/card0/
codec#3  id  pcm3p
