Hi,
I found how to simply upstream the sound of the pc card to Rune (Windows). So here is the way:
* Rune Settings - UPnP / DLNA -> ON
* Install
* A new logo appears near the clock, simply right click on it and select Stream to: RuneAudio UPnP
There is a lag of 2 sec. (so it's of no use for movies), the sound is what it is, and you get ALL the sounds of the laptop (outlook notifications a.o.)
You can disable the sound on the pc through Windows volume control (but not at the software level)
Best,
Yann
