Hello you should look at

http://wiki.gentoo.org/wiki/Radeon

then :

http://wiki.xbmc.org/index.php?title=Archive:HOW-TO:Setup_audio_over_HDMI_on_nVidia_GeForce/nForce_controller .


Because I Finally sucess to have sound over HDMI after searching over tne net during 3 nights

I followd this link who helped me :
http://wiki.xbmc.org/index.php?title=Archive:HOW-TO:Setup_audio_over_HDMI_on_nVidia_GeForce/nForce_controller .

The normal link ( http://wiki.gentoo.org/wiki/Radeon#Audio_over_HDMI ) for my VGA card did not help me to get the sound but to configure the right kernel.
Your kernel must be > 3.3 mine is 3.4.14.14

Now I have sound but it's very bad (craking), I am still looking how to configure to have a good sound

May card is an AMD R9 280x (tahiti ).

my asoundrc file is
Code:

pcm.dmixer {
   type dmix
   ipc_key 1024
   ipc_key_add_uid false
   ipc_perm 0660
   slave {
      pcm "hw:1,3"
      rate 48000
      channels 2
      format S32_LE
      period_time 0
      period_size 1024
      buffer_time 0
      buffer_size 4096
   }
}
 
pcm.!default {
   type plug
   slave.pcm "dmixer"
}


I created a /etc/asound.conf file with :
Code:

cm.!hdmi-remap {
  type asym
  playback.pcm {
    type plug
    slave.pcm "remap-surround71"
  }
}
 
pcm.!remap-surround71 {
  type route
  slave.pcm "hw:1,3"
  ttable {
    0.0= 1
    1.1= 1
    2.4= 1
    3.5= 1
    4.2= 1
    5.3= 1
    6.6= 1
    7.7= 1
  }
}

in /etc/modprobe.d/alsa.conf I write :
Code:

 #Audio over HDMI
options snd-hda-intel

My Aplay -l file :
Code:

**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC889 Analog [ALC889 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
