Hi Alex,

In Tizen IVI we are using pulseaudio as the sound backend.
For command line utility we usually use paplay

This is how we can handle audio policy in a nice way in user space
(we can tap into pulseaudio and do all kind of stuff).

If you want to use specifically alsa, google for dmix issues and
You probably find info how to bypass pulse. But you will loose
The policy functionality of Murphy and possibly some other audio
Features like Bluetooth.

Br,
Jaska

P.S. I don’t know what browser you are using, but there’s a bug
In latest Tizen ivi images (TC-1731) where crosswalk runtime will use
alsa if Pulseaudio is not already started. This will cause all kind of
nasty issues…

Subject: question about multiple audio streams with ALSA


Hi, All
 I have a question about how to achieve multiple audio streams with ALSA in 
Tizen.
 I used my browser to play  music, and pressed the pause.Then, play a PCM in 
shell,
 But get the error as below:
 ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave.
 Is there any extra setting I have to do ?

Thanks
Alex Rong
