I developed Dual Audio Output support for XBMC

Hi, I need two audio output simultaneously, One for AV receiver, one for TV analog audio input. So I developed Dual Audio Output support for XBMC.

How do you think this feature? Is it usable?

Currently the GUI sound only output to original first device.


Add TWO Audio Output support, thus you can use the 2nd output device of
the sound card (e.g., S/PDIF and analog) or use another sound card for
simultaneously output. The 2nd audio output can set to disabled.


For example, you can set the original output to Analog 2.0 so it can be
connected to a TV, Speaker or Earphone, etc; Set the 2nd output the AV
Receiver using Opical/Coax S/PDIF passthrough mode. COOL?

Both output for music playback.



Both output for video playback.


I build a Windows DirectX version, binary patch files are shared:

10.1-Dharma Final:
Windows(DirectX): XBMC-10.1-dx-DualAudio.zip
Other OS Platform: Pls build from the modified source files below by yourself :-)
11.0-Eden:
Windows(DirectX): XBMC-11.0-dx-DualAudio.zip
Other OS Platform: Pls build from the modified source files below by yourself :-)


I only release the Windows binary file XBMC.exe for downloading, you can install a corresponding XBMC version and use this XBMC.exe to simply overwrite.
I do not have other OS enviroment, so I do not build other OS version binary. Please build from the source by yourself. If anyboby wanna build and upload somewhere and give me the link, I'll be glad to put the link here.

Under windows, you'd better both select Directsound deivces or select one Directsound and one WASAPI device, you can not both select WASAPI devices because only one WASAPI device is permitted in a windows process.

The full modified source files are here(Not a diffed patch file, simply extract and overwrite original before build):
10.1-Dharma: xbmc-10.1-dualaudio-mod-source.zip
11.0-Eden: xbmc-11.0-Eden-dualaudio-mod-source.zip
