Public bug reported:
I did a fresh install of jaunty on my HP DV9812EG Notebook, but HDMI
Audio out isn't working.
In the beginning i had ALSA Version 1.0.18 installed, which came with
Ubuntu 9.04. Even tough the lastest proprietary geforce driver (NVIDIA-
Linux-x86_64-185.18.14-pkg2.run) seems to work properly, there was no
HDMI sound. Thus, I updated to the lastest Kernel 2.6.30 (official
release, no RC) and ALSA 1.0.20, but it didn't change anything. The HDMI
"device" can't be recognized even tough it should be there.
ALSA 1.0.20 was configured with the following command:
./configure --with-cards=all --with-card-options=all --with-
sequencer=yes && make
Under Windows Vista Everest finds the following soundcard and HD Audio
Modem:
Conexant Cx20561 @ nVIDIA MCP65 - High Definition Audio Controller
Modem HDAUDIO Soft Data Fax Modem with SmartCP
"hwinfo --short" under ubuntu 9.04 confirms this, but "aplay -l" list
only these two audio devices (it should be three at least):
ren...@riese:~$ aplay -l
**** Liste von PLAYBACK Geräten ****
Karte 0: NVidia [HDA NVidia], Gerät 0: CONEXANT Analog [CONEXANT Analog]
Untergeordnete Geräte: 1/1
Untergeordnetes Gerät '0: subdevice #0
Karte 0: NVidia [HDA NVidia], Gerät 1: Conexant Digital [Conexant Digital]
Untergeordnete Geräte: 1/1
Untergeordnetes Gerät '0: subdevice #0
ren...@riese:~$
So what's missing is something like this:
Karte 0: NVidia [HDA NVidia], Gerät 3: NVIDIA HDMI [NVIDIA HDMI]
Untergeordnete Geräte: 1/1
Untergeordnetes Gerät '0: subdevice #0
"aplay -L" shows this result:
ren...@riese:~$ aplay -L

HDA NVidia, CONEXANT Analog

So again there is missing something like:
hdmi:CARD=NVidia,DEV=0
HDA NVidia, NVIDIA HDMI
HDMI Audio Output
I even tried to go back to ALSA 1.0.19 but it is not possible to
./configure the original alsa-driver package (there was an error, but i
don't remember which). As an alternative i tried to install the linuxant
deb-version of ALSA (alsa-driver-linuxant_1.0.20.3_all.deb) and the
realtek version (realtek-linux-audiopack-5.11) but both versions didn't
work.
So this must be a bug, because everything else works fine (e.g. HDMI
Video out, Laptop Speakers, Ear-Plug-Audio out...)
Unfortunately, to find and eliminate the bug, I can contribute only with
some other information:
