Bug Description
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-
ALSA 1.0.20 was configured with the following command:
./configure --with-cards=all --with-
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):
rennie@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
rennie@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:
rennie@Riese:~$ aplay -L

HDA NVidia, CONEXANT Analog
Default Audio Device
front:CARD=

rennie@Riese:~$
So again there is missing something like:
hdmi:CARD=
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-
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:
Result of "lspci | grep -i audio!":
-------
rennie@Riese:~$ lspci | grep -i audio
00:07.0 Audio device: nVidia Corporation MCP65 High Definition Audio (rev a1)
...and the result of "cat /proc/asound/cards"
rennie@Riese:~$ cat /proc/asound/cards
0 [NVidia ]: HDA-Intel - HDA NVidia
rennie@Riese:~$
Result of "alsactl init NVidia":
-------
rennie@Riese:~$ alsactl init NVidia
