Hi, I want to stream on my Twitch channel live stuff I do with Sonar. 

I know how to stream & put sonar in the screen but my only problem is with AUDIO.

It's like Sonar don't play the audio outside of the program. Like if I'm listening youtube,spotify,windows sound or anything, I will see the audio meter go up & down(Windows meter in the bottom) but when Sonar play the windows meter just doesn't move.

I've tried VB Cable,Voicemeeter but doesn't seem to work, or i'm not doing the right thing.

Thanks  !

Hi, and welcome to this forum. Which version of SONAR do you have? If you have the latest Platinum version, I think you could use AUX tracks. Regarding playback (while SONAR is open), have you tried to check share drivers with other programs in Preferences (P), Audio, Playback and Recording?
All the best.

Zargg71 , I got Sonar X3 Producer. I tried Share drivers with other programes and it doesn't change nothing. When I press PLAY on Sonar the sound bar in the windows mixer doesn't move at all ( And when I MUTE the mixer all the volume stop EXCEPT sonar. ) I don't understand !
