ofSoundPlayer not working setVolume (Pi3 with a hifiberry dac+)[solved]


I am on Raspberry Pi3 with a hifiberry dac+ using lastest version 0.9.8 Openframeworks.
In my app using ofSoundPlayer a wav file is playing, but I cannot setVolume. It is not responding to any value (0-1) always is playing at full volume even If i set to 0.

Only see is the following warning:
AL lib: (WW) alc_initConfig: Failed to initialize backend “pulse”

I did try what was suggest at this post: Error running soundPlayerExample on the Pi but it did not help.

I got working updating to lastest kernel Jessie 4.9 and then started to work fine.

The warning from AL lib still appears but not seem to be important.
