hey guys,

i cant get the hdmi sound working over hdmi,
the alsamixer didnt recognize the HDA nvidia device,

ubuntu minimal with xbmc and xbmclive works all very nice.

i am very new to linux so i dont really know what i am doing here
so i did this tutorial

so i installed new alsa drivers
downloaded them from the alsa-project.org
and compile / installed them wiith: ./configure, make , make install.
worked all well but after reboote i get:

xbmc@xbmclinux:~$ aplay -l
aplay: device_list:223: no soundcards found...
xbmc@xbmclinux:~$

then i reinstalled the alsa stuff with:
sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils
sudo apt-get install linux-sound-base alsa-base alsa-utils

still no soundcard found with aplay -l

xbmc@xbmclinux:~$ modinfo soundcore

the kernel is running i think.
xbmc@xbmclinux:/$ sudo grep 'audio' /etc/group
audio:x:29:xbmc

xbmc is allowed to use the uadio devices i think

snd_hda_codec_nvhdmi are listed in it..

lspci -v gives me :
05:00.1 Audio device: nVidia Corporation High Definition Audio Controller (rev a1)
Flags: bus master, fast devsel, latency 0, IRQ 11
Memory at f2000000 (32-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>

so the system knows the soundcard somehow
what is this access denied??

xbmc@xbmclinux:/$ sudo modprobe snd-hda-codec-nvhdmi
WARNING: /etc/modprobe.d/lirc_imon.conf line 3: ignoring bad line starting with '</iframe></noscript></object></layer></span></div></table></body></html><!--'
WARNING: /etc/modprobe.d/lirc_imon.conf line 4: ignoring bad line starting with '<script'
xbmc@xbmclinux:/$

doesnt sound good..

i configured sudo nano /etc/modules

and wrote snd-hda-codec-nvhdmi in the last line to get the drivers loded after reboot but didnt work

i could really need some help here 8)

i used this setup.sh to get the newest alsa drivers, atleast 1.0.23 is required for hdmi audi with a gt210/220

i did the following steps:
- remove pulse audio
- install alsa: apt-get install esound
this installs all required packages
on ubuntu earlier 10.10 you need to upgrade linux-alsa-driver-modules-2.6.32
register this ppa: https://launchpad.net/~ubuntu-audio-dev/+archive/ppa
- create a whatever.conf file in /etc/modprobe.d/ or append a line to alsa-base.conf

Code:

options snd-hda-intel enable_msi=0 probe_mask=0x1,0x2

finding out the right bit mask is a little try and error: see
http://www.kernel.org/pub/linux/kernel/p...Audio.html
inspect your syslog and change the mask if there are errors, the line above worked for my gt220
- run gstreamer-properties and set to alsa, this way you get system sounds
- you need /etc/asound.conf, mine tooks like this

Code:

pcm.!default {
    type plug
    slave.pcm "dmixer"
}

pcm.dmixer  {
    type dmix
    ipc_key 1024
    ipc_key_add_uid false
    ipc_perm 0660
    slave {
        pcm "hw:1,3"
        period_time 0
        period_size 1024
        buffer_size 4096
        rate 48000
        channels 2
    }
    bindings {
        0 0
        1 1
    }
}

ctl.dmixer {
    type hw
    card 1
}

you might have to change card and device
- do not forget to set resample rate to 48000 in xbmc's advancedsettings.xml
