Hi Ahmed

Maybe can't.. sorry.
Before enable ffmpeg, Chromium also has the same decode very slow issue, please 
see the details here, 
https://bugs.chromium.org/p/chromium/issues/detail?id=424174

However, as the description in 
https://crosswalk-project.org/jira/browse/XWALK-7307 and my patch 
https://github.com/crosswalk-project/chromium-crosswalk/pull/398,
Crosswalk has to disable ffmpeg for the property codec problem.

So the result is that Crosswalk can support mp3 and other property codec, but 
with the decode slow issue...

Best Regards :)

One last question, I noticed that long files take very long time to decode 
(around a min). is there a way to make this faster. (Certain encoding or 
certain plug-in or certain technology or etc)

Thanks in advance :)

Thanks for replying, I am using Phaser. Phaser uses WebAudio
I tried these stuff and it works thanks I think I will need to handle device 
events because the game music doesn't stop at all.

Hi Ahmed,

Not sure which way you are using the audio in your game, please refer to:

https://crosswalk-project.org/jira/browse/XWALK-7307 AudioContext 
decodeAudioData() does not work on Crosswalk 19 upwards
https://crosswalk-project.org/jira/browse/XWALK-6874 Audio Playback not working 
with --enable-unified-media-pipeline flag

We've fixed some audio issues in Crosswalk 23 beta, please try:

          <preference name="xwalkVersion" 
value="org.xwalk:xwalk_core_library_beta:23+" />

Subject: [Crosswalk-help] sound is not playing on android only

Hello Everyone,
I am Ahmed Khalifa, an indie game developer. I am working on my game C-Square 
using Phaser but I have problems with compiling the android version using 
cordova with crosswalk plugin.
I compiled my game using cordova and it is working fine but some devices were 
having performance issues so I decided using crosswalk now everything is super 
fast but no audio in the whole game. The game works perfectly on iOS.
The sound files are mp3 files (32-bit float, Stereo, 44100Hz)
here are the parameters using for crosswalk

<plugin name="cordova-plugin-crosswalk-webview" spec="~2.2.0">
<variable name="XWALK_VERSION" value="22+" />
<variable name="XWALK_LITEVERSION" value="xwalk_core_library_canary:17+" />
<variable name="XWALK_MODE" value="embedded" />
<variable name="XWALK_MULTIPLEAPK" value="true" />
</plugin>
<preference name="xwalkCommandLine" value="--ignore-gpu-blacklist" />


Any help is appreciated as I have been stuck in this problem for more than a 
week.

Thanks
Ahmed Khalifa
