How to setup NVidia HDMI Audio on LinuxMCE 1004
It is assumed that
sudo aplay -l
Does NOT list your HDMI audio devices. IF that is the case then
sudo apt-get install linux-backports-modules-alsa-`uname -r` reboot
They should now be listed. Check with:
sudo aplay -l | grep -i 'hdmi'
You will likely have hw0 devices 3,7,8, and 9. It is almost always 3 or 7 on the id41, and seems to be completely random which. Others output on 9... others output on everything. Configured correctly, they should look something like:
card 0: NVidia [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI] card 0: NVidia [HDA NVidia], device 7: NVIDIA HDMI [NVIDIA HDMI] card 0: NVidia [HDA NVidia], device 8: NVIDIA HDMI [NVIDIA HDMI] card 0: NVidia [HDA NVidia], device 9: NVIDIA HDMI [NVIDIA HDMI]
What is important to us here is the card number, and the device number. IF HDMI cards list as card 1: You will have to add either
options snd-hda-intel model=auto
or
options snd-hda-intel enable_msi=0 index=-2
to /etc/modprobe.d/alsa-base.conf to place the HDMI audo as card 0. For some reason, it has to be card 0. After making this change, you can try
sudo alsa -f reload
But sometimes this is problematic, and a reboot is preferred.
You can test which will work for you with:
sudo speaker-test -c 2 -l 1 -t sine -D hw:0,7
etc based on the output of aplay where the 0 is the card and 7 is the device in our example.
Now getting that to stick is another trick. In /usr/pluto/templates/asound.conf I would replace %MAIN_CARD% with 0,7 as per the example or whatever yours turns out to be.
pcm.asym_hdmi {
type asym
playback.pcm "hdmi_playback"
capture.pcm "plughw:%MAIN_CARD%"
}
Lastly we will add a command in the /usr/pluto/bin/LaunchOrbiter.sh script to let mplayer play a sound-file on startup of the orbiter. This sound should exist on all installs, and is the smallest least intrusive one pre-packaged on the system. Its the line right below the xset m command
## Run Orbiter xset m 2 2 DISPLAY=:0 mplayer /usr/share/sounds/pop.wav if "$Valgrind" == *"$Executable"* ; then $VGcmd "$Executable" "$@" Orbiter_RetCode=$? else "$Executable" "$@" Orbiter_RetCode=$? fi
Please report back to L3top with your results.
