Hello people, a search my problem but no find some solution for me, a few months i configure my new ZBOX ID41 to run with XBMCLive, and this is fine, i have the problems with the sound over HDMI, but the forum and the site help me.


My Hardware have 3 sound outputs,
HDMI, OPTICAL and Analog P2


I want to run the sound over all the sound output of my device, i seash on forum e i make the sound output in all outputs. (HDMI, OPTICAL and ANALOG FRONT)

I use the asound.conf of "asound.conf_double-xs35gt.sample" whit no modifications
I confiogure the audio setting like this topic says:
www.openelec.tv/forum/14-general-help-an...box-ad02-hdmioptical

Work fine, all the outputs have sound, but have a problem


My TV only support 2.0 sound and if i play DTS, i have a strange noise.
I have one receiver with DTS and 5.1 support
And have some stereo phones


So i want toh bind and configure my Alsa toh each output and make they a multiple sound


HDMI -> 2.0, DTS off and AC3 off (decoded and downmixed)
ANALOG -> 2.0, DTS off and AC3 off (decoded and downmixed)
OPTICAL -> 5.1, DTS on and AC3 on (passedthrough)

And i want they 3 play simultaneously in multiple sound.


Whenever I change the file asound.config, a make some crap.

Can anyone help to make this, it is possible

There is a patch for Dharma that enables dual audio output and allows you to select the output format for a specific audio output. The author has said that they will update it for Eden once its released. I have read that its possible to achieve what you want through ascound.conf but there are some limitations. Please post any progress that you make here as this is one feature I really want in xbmc but I would rather have it done on a system level as the xbmc devs have said that this kind of functionality will never be part of xbmc.

EDIT: Pulse audio allows you to output to multiple outputs but Ive never tried it..

Your getting the strange noise because your TV doesn't support dts.
