No analog 5.1 Sound with onboard sound(chip)

[el_bastardo]

Hi folks,

got some nice shuttle xpc with an SN25P Mainboard (socket 939 with an AMD 64 3000+), Soundchip is an VIA VT6307.

For setup i used the latest generic build (OpenELEC Beta - Generic x86_64 Version:3.95.5).
System works really nice except the analog 5.1 audio output.
In systemsetting <> Audio i can chosse some HDMI devices, 2.0 Audio via the TV speakers works fine.
I also can choose the onbord sound (3 different entrys) none of them will give me audio.

OpenELEC (official) Version: 3.95.5

So, how to get that analog output to work??

There's no such thing as multi-channel analogue audio so I'm guessing the three non-HDMI soundcard outputs listed above can be used for a) FL & FR, b) RL & RR, c) CTR & SUB to create a multi-channel (5.1) analogue card. To make this work in OpenELEC you'd need to do some asound.conf trickery to create a virtual composite audio device (so there is a single audio interface that can be selected in XBMC) that maps the virtual channels to their physical equivalents - I suspect the Windows drivers for the soundard do the same kind of thing. I've no idea what that asound.conf file would like like, but now you have a clue to Google.

.. some kind a hint, anyway ...

maybe anyone can explain waht i have to put in the asound.conf.

[el_bastardo]

Any sugestions? Sound still not working ...

In v3 of OE I tryed many way to have 5.1 or 7.1 sound but with no lucky.
I try now the 4.0.4 to check if work with my sound card.

Tnxs for your comment.

I´m now using 4.0.7 and audio trouble again ...

Sometimes all speakers work (stereo upmix) whenn i play some mp3, sometimes only bass an center work.
Same thing with streamed movies from the web.
Sometimes no analog audio, alle speakers are silent ...

I have no clue why ...
