Sad, but GMS 1.4 tools does not provide correct playback on some browsers, that causes problems while making HTML5 mobile games. The problem is solved by use an external specialized library. Here correct playback is provided with special "howler.js" library v2.0.13 from https://howlerjs.com/
Pack includes extension itself with library, as well as source code of game example The software is provided "AS IS", without warranty of any kind ( see "Howler.js" documentation here https://github.com/goldfire/howler.js/blob/master/LICENSE.md )
Before purchasing please read the documentation (https://github.com/goldfire/howler.js#documentation) and test GM game example (http://asteroidgamers.com/extensions/GMS_howler_audio/ ) to determine compartibility with different browsers.
Also correct playback was tested in mobile browsers on devices:
Note that on some mobile devices the sound will not be heard until you tap on the screen with the game running. The reason for this is described in the documentation on Howler (option mobileAutoEnable)
