Hello,
I have managed to get my Zotac IONITX NVidia ION board to produce sound over
HDMI finally. When I run
speaker-test -Dhdmi:NVidia -c8 twav
I see that my amp correctly identifies the sound as 7.1. The problem is the
speaker channel assignments are wrong. Main problem seems to be the right
speaker not being used at all. My sound system is a Sony HT-CT500 which is
3.1. All sounds come from Left, Center and LFE.
My .asoundrc file is as follows:
pcm.dmixer {
type dmix
ipc_key 1024
ipc_key_add_uid false
ipc_perm 0660
slave {
pcm "hw:0,3"
rate 48000
channels 8
format S32_LE
period_time 0
period_size 1024
buffer_time 0
buffer_size 4096
}
}
pcm.!default {
type plug
slave.pcm "dmixer"
}
My asound.conf file is as follows:
pcm.!hdmi-remap {
type asym
playback.pcm {
type plug
slave.pcm "remap-surround71"
}
}
pcm.!remap-surround71 {
type route
slave.pcm "hw:0,3"
ttable {
0.0= 1
1.1= 1
2.4= 1
3.5= 1
4.2= 1
5.3= 1
6.6= 1
7.1= 1
}
}
I have also changed HDA-Intel.conf file as shown in
http://pastebin.com/f2e38265
I'm running ubuntu 10.10 with ALSA 1.0.23.
Thanks for any guidance.
Selim
