That's strange.. I think you should really check everything, because with the ION330 it is a known issue that the channel mapping is wrong, with the center comping out of the Rear Left speaker RL plays through the center. The same is true with Rear Right and the LFE channel.

However, you seem to be having a completely different issue. Download the file in this post: http://forum.xbmc.org/showthread.php?tid...pid1259665

And test it. First without any asound.conf or .asrounrc, and keep trying from there. When you are done post the results. Also check that your center channel is working and that the receiver speaker config is setup up properly.

That is a nice file to test it with, thanks!

First test without .asoundrc. I will update this post after more testing

Result with .asoundrc removed:
Audio output = HDMI
Speaker Configuration = 5.1.
Audio output device = HDMI

format is input > output

FLAC 7.1
left/right front > left/right front
center > left rear
left/right surround > left/right front
left/right rear > no sound

FLAC 5.1
left front > left front
center > left rear
left/right rear > no sound

AC3 5.1
left/right front > left/right front
center > no sound
left/right rear > left/right rear

AAC 7.1
left/right front > left/right front
center > left rear
left/right surround > no sound
left/right rear > no sound

AAC 5.1
left/right front > left/right front
center > left rear
left/right rear > no sound

TrueHD
left/right front > left/right front
center > left rear
left/right surround > left/right front
left/right rear > no sound

Second test with below in .asoundrc

Code:

pcm.!default {
    type plug
    slave {
        pcm both
    }
}

pcm.both {
    type route
    slave {
        pcm hdmi
    }
       ttable.0.0 1
       ttable.1.1 1
       ttable.2.4 1
       ttable.3.5 1
       ttable.4.2 1
       ttable.5.3 1
}

Audio output = HDMI
Speaker Configuration = 5.1.
Audio output device = Default (HDA NVIDIA, HDMI 0)

What has changed is that for all audio formats:
left/right front > left/right front
center > no sound
left/right surround > left/right rear
left/right rear > left/right rear

Since I have no confirmation that my center speaker works, it means that either my center speaker has a physical problem or there is still something missing in the settings.
I am going to check the wires and report back later.

Test number 3:
Believe it or not, one of the wires was not connected to the center speaker. I guess I have my cat to blame.
So I ran by the formats again. Everything seems to be in order now, except for one thing:

AAC 7.1
left/right front > left/right front
center > center
left/right surround > left/right rear
left/right rear > center

Is there anything to solve that or do the setting affect all formats?

[PatrickVogeli]

For 7.1 you have to add:

ttable.6.6 1
ttable.7.7 1

Check if that works.

[Onnib]

I have added

ttable.6.6 1
ttable.7.7 1

but that didn't work for AAC 7.1
FLAC 7.1 and TrueHD did work properly, but they did so even before I added above two lines.

[PatrickVogeli]

Could you recheck if it really only comes out of the center or on other channels too? This may be a complete different thing, could be a bug in the way 7.1 AAC is downmixed to 5.1 in XMBC.

[Onnib]

Ok I will check this out later. For now everything seems to be back in order.

Thanks a lot for the help guys!
