I doubt this is to do with Construct 2 because it 1) works on other devices, suggesting our code is correct and 2) it is not normal for web content to actually crash the app, that usually indicates a failure in the browser engine or OS.
It is also probably unrelated to the decodeAudioData chrome bug mentioned in the Crosswalk bug thread, since your sound is categorised as music so probably does play with the audio tag already instead of with Web Audio decoding.
Unfortunately it will be difficult to report this to anyone unless you can reproduce on stock Android. CyanogenMod is not officially supported by Google so unless you can reproduce it on a Google-supported device then I doubt anyone will look in to it.
