Re: OpenSL - Audio Session ID for 3rd party equalizer apps

The Nexus is running some sort of Vanilla Android build then I guess(?). The point being that its music player might not be applying any effects of its own, while the one on Samsung's phones probably is. The AudioFlinger in Jellybean will disable all effects applied to session 0 when someone attaches an effect to a session other than 0.

It's mentioned at

I'm still looking for this info as well.  

I released an audio visualizer that uses audio session 0 to get audio data. It works great on my Nexus S running Android 4.1, but I've received many complaints from Galaxy Nexus and Galaxy S3 users that say that it flatlines under most conditions.

Where did you see that audio session 0 is being deprecated?

Thanks.

When using OpenSL to play audio in native code how does one retrieve the Audio Session ID so that we may pass it to 3rd party equalizer apps? Basically the NDK equivalent of this function in the SDK: http://developer.android.com/reference/android/media/MediaPlayer.html#getAudioSessionId()

I looked everywhere and it does not seem possible. Furthermore the global audio session 0 is being deprecated and no longer works in Jellybean with music players that use the NDK for playing audio.
