Hi, Sound card should appear as sink (or many sinks)in pulseaudio, to where you can then explicitly route.
However there are exceptions: 1) If your extra sound card is mapped as separate alsa pcm, pulseaudio should automatically create a sink for you. 2) If the extra output you want to route, is a alsa "sub pcm" like hdmi is in many pc sound cards, you have to manually load these in pulseaudio configuration or create a multisink profile in pulseaudio. The above things you can check with aplay or amixer commands. You can give the routing target to gstreamer as gsreamer pulsesink "device" property. However I'm not sure if this is anyway mapped through to QT. We haven't officially so far supported qt very well. It would be helpful if you could give more concrete example of your use case and hw configuration. br, Jaska 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. Unfortunately the documentation is somewhat scarce. Somebody else was asking the similar question and I'll try to put some tutorial for this to Murphy web pages as soon as I'm able. ________________________________________ From: IVI [[email protected]] on behalf of Yang Andy [[email protected]] Sent: Monday, December 15, 2014 6:33 AM To: [email protected] Subject: [IVI] [TizenIVI3.0]Question about Multi Audio stream routing Hi everyone This is a question about Multi audio stream routing in TizenIVI3.0 . [Use Case] There are two media players playing different mp3 files at the same time. I want to rount them to different sound card. [Soft arch] HMI--->QT--->gstreamer--->pluseaudio--->alsa [Question] I think i can use paplay command to play the file to particular sink, but in the TizenIVI MultiMedia software architecture,How to route them to different sound card? Where should I config the route? Gstreamer or pluseaudio or alsa?
