Hi Jaska Thank you very much for your reply.

My use case is: I want to play different mp3 files for driver and passanger with two different applications or the same application which is deployed by two QTMultiMedia components. Driver:HMI-->QT-->GStreamer-->PulseAudio-->ALSA--SoundCard1 Passanger:HMI-->QT-->GStreamer-->PulseAudio-->ALSA--SoundCard2 Is it possibility to modify Gstreamer pipeline of QT MultiMedia Framwork for fulfill my requirement? > P.S. there are possibilities to do "automatic" routing in a module inside > pulseaudio (pulseaudio-module-murphy-ivi). So you can route based > on your binary name or some other properties you have given to pulseaudio. What is the meaning of other properties?Could you give me more detail? And if i use pulseaudio-module-murphy-ivi, which modules do i need to modify except modifying xxxx.lua configure file?
