If that doesn't work...

New page

== XBMC Live [Dharma] 10.1 ==

'''April 11, 2011'''

EVGA GT210 - added file "sudo nano /etc/asound.conf" for menu sound

pcm.!default {
type plug
slave {
pcm "hw:0,3"
rate 48000
}
}

In XBMC
System => System => Audio output
[Both Audio Out and passthrough] on custom "plughw:0,3" [Card 0, Device 3 from "aplay -l in telnet"]

Update: Didn't need to put custom "plughw:0,3" "HDA Nvidia hdmi" works also.

== Before You Begin/Notes ==
This guide assumes that you have a GeForce G210, GT220, or GT240 card, are using a reasonably up-to-date system, and that you have at least the nVidia 190 series proprietary drivers installed.

== Getting ALSA ==

Team iQuick also has a PPA with the latest ALSA drivers and Ubuntu Audio Dev PPA has the necessary kernel modules for Lucid (What XBMC-Live is based on).

add-apt-repository ppa:team-iquik/alsa
add-apt-repository ppa:ubuntu-audio-dev/ppa
apt-get update
apt-get upgrade
apt-get install linux-alsa-driver-modules-$(uname -r) --force-yes

Or if you haven't yet installed ALSA:

apt-get install alsa-base alsa-utils linux-alsa-driver-modules-$(uname -r)

-----
Compiling from source:

ALSA 1.0.23 contains the new drivers. You can download, compile, and install it without further additions, and proceed to configuration. The drivers are also included with the 2.6.34 Linux kernel; users of this kernel should be able to skip straight to configuration as long as the <tt>snd_hda_codec_nvhdmi</tt> module (and its dependencies) are available.

In general, you can choose to [http://www.alsa-project.org/main/index.php/Download install ALSA from source] or use the [http://ubuntuforums.org/showthread.php?p=6589810 ALSA Upgrade Script]. Alternatively, you can find updated packages for your distribution. Note that only the ''drivers'' from 1.0.23 or later are required; updating the ALSA userspace tools is optional.

Ubuntu users make sure to remove the <tt>linux-backports-modules-alsa-`uname -r`</tt> package or your newly compiled ALSA drivers will be ignored.

== Setting Module Options ==
You may need to set options in <tt>/etc/modprobe.d/sound.conf</tt> depending on your card. The general format is:

options snd-hda-intel ''OPTIONS''

Please list your card and working module options below, along with the working device(s). Note that these options may change with future revisions and refinements to the drivers.

*I'm asserting that any GT210/GT220/GT240 should use plughw or plug to allow AC3 passthru. I'm not an alsa expert but the following link suggests plug should be used. However I found this info after getting it working with plughw and I'm loath to break a working system to test it (volunteers?). [http://www.alsa-project.org/main/index.php/DeviceNames Alsa Recommened DeviceNames]

Once you've set your module options, proceed to "PulseAudio Configuration" (if applicable) or "Finishing Configuration".

=== If that doesn't work... ===
if probe_mask doesn't work for you (it didn't for me, one boot my GT220 came up first instead of second, but next reboot it came up second without me touching the probe_mask parameter, you can try this (which works reliably for me):

options snd-hda-intel enable_msi=0 index=-2

or

options snd-hda-intel enable_msi=0 index=1

or
*Disable Intel HDA module
''nano /etc/modprobe.d/blacklist-hda-intel.conf''
blacklist snd_hda_intel

The first one tells snd-hda-intel "don't grab index 0", while the second one says "grab index 1" (so even if you disable your on-board card, your GT220 is still going to be hw:1,7), the third one kills the card from even being recognized(harshest method).

I have to make a <b>BIG NOTE</b> that I don't have another Nvidia sound card on the motherboard, and that's why the above works for me. It won't work if you have an integrated nvidia sound AND a GT220.

For the case with Nvidia motherboard audio + GT210/GT220/GT240 HDMI don't be discouraged by the note above. I added the "enable_msi=0 probe_mask=0xffff,0xfff2" to /etc/modprobe.d/alsa-base.conf (Ubuntu 9.04) but I'm not 100% sure that's even necessary with 1.0.23. After that my HDMI audio showed up as plughw:2,3.

If multiple nVidia devices still show up with the recommended probe_mask, you may need to adjust it. More information about selecting the correct parameters for this option can be found in [http://www.kernel.org/pub/linux/kernel/people/tiwai/docs/HD-Audio.html#_codec_probing_problem Takashi Iwai's documentation for the High-Definition Audio drivers].

== XBMC Configuration ==
It may happen that even the PulseAudio configuration doesn't work. For example with the Point of View GeForce G210. In this case, simply set up the module options as described above, and then go into the XBMC Settings -> System -> Audio, select a custom device for audio and insert plughw:X,7. The audio should now work!

== PulseAudio Configuration ==
If using PulseAudio, add the following line to /etc/pulse/default.pa:

load-module module-alsa-sink device=hw:1,3

Where 1,3 is card#,device# for the nVidia HDMI output given by <tt>aplay -l</tt>.

== Finishing Installation ==
Now, reboot your system. Using <tt>`alsamixer'</tt>, select your nVidia card (select it from the F6 menu, or use the <tt>-c</tt> option) and unmute the S/PDIF output (press "m"; the box should change from "MM" to "OO".) Enjoy!

If you have no sound, you should ensure that your user is a member of the "audio" group:

$ groups
adm dialout cdrom '''audio''' video plugdev mythtv lpadmin

Consult your distributions' documentation to determine how to add users to groups.

If you still have no sound, you can try editing/creating /etc/asound.conf:

pcm.!default hdmi:NVidia
pcm:iec958 hdmi:NVidia

Ensure that <tt>$HOME/.asoundrc</tt> is empty, does not exist, or does not override these settings. Reboot.
