Control device audio volume?

Any idea how it's done ?

as far as i figured i have to import the audiomanager class from the qnx system and then call the setOutputLevel function passing in the nuber i want it to be but it doesn't seem to work :smileyfrustrated:

PS: i'm running 10.0.9.388 soft on my DevAlpha and compiling using the 3.0.0 SDK

Howdy!

 

import the following:

 

import qnx.system.AudioManager;

import qnx.system.AudioOutput;

 

in your desired code block add:

 

AudioManager.audioManager.setOutputLevel(0.1, AudioOutput.SPEAKERS);

 

The second argument can be null and it will set whatever output is currently being used, but I like to be explicit!  Next, add the following to your bar-descriptor.xml:

 

<permission>set_audio_volume</permission>

 

I hope that helps!  Let me know how this works for you.

 

Cheers!

Thx man, setting them permissions did the trick :Clap: Though the value that worked was from 0 to 100, not 0 to 1 like it says in the reference :Beta1:

Nice!  Yeah, when I set it to 0.1 it certainly did look A LOT LESS than 10% :smileytongue:

 

I'll check with the AIR SDK team to see which will be the final implementation.  For consistency with ActionScript I imagine it will eventually be 0 to 1 as opposed to 0 to 100, so be sure to be prepared for that.

 

Glad I could help!
