[PROBLEM] Both HDMI and Analog output on Raspberry Pi XBMC

[slingshot27]

Hello,

I have a hearing problem and listen to the movies on a device that is connected to the analog input of the Raspberry Pi. My wife would also like to hear sound and her sound is given by the TV via HDMI.
Now the problem is that the sound goes through HDMI or analog output.

It would be great if the audio through both HDMI and analog would be sent so we both can enjoy the movie. Is this possible?

On the internet I found the link below, only I have no linux experience. Is it someone managed to get this working?

Thank huge thanks for the help!
