    I have a very short class I created (my first Responsive design) and the sound files are MP3.  Works great on the computer or a tablet, but not on my phone (Droid).  So based on what I was reading, I needed to download an MP3 player for my phone – which I did.  Still no sound.  I’m kinda phone challenged, so it’s possible I’ve overlooked something.  Should I pick a different format for the SmartPhone classes?

    You don’t need to download anything on your phone. It should just work in browser. However, autoplay will not work in browser (this is imposed by phone manufacturers, nothing can be done about it) so you have to create a Play Audio button in your course that learners have to press for the audio to play.

    You can auto-play audio an android phone if you change a setting in the chrome browser. In the address bar type chrome://flags

    This will open up internal chrome settings. scroll down until you find Gesture requirement for media playback. By default it is enabled. Tap Disable and auto-play will work.

    Keep in mind, however, that auto-play is disabled by default because data usage on mobile devices can be inadvertently incurred. You might want to go back into the setting and re-enable it after testing.

    More importantly, keep in mind that the “chrome://flags” bit will have to be performed by every learner on every phone, which makes it pretty useless for real world production.

    To Sergey’s point this is obviously not an acceptable solution as you cannot remotely alter these settings. I provided it to you because as a developer you should have every tool at your disposal.

    Also to reiterate what Sergey initially said, you should not have to do anything to get MP3’s to play on an android phone. I’d look at the MP3 file as either corrupt or incorrectly encoded.

    Thank you for all the wonderful responses!  I will try the auto-play button.  And nice to know about the flags thing.  I will also check that out.  I’m so glad there are so many wonderful experts out there to help me!

    At the Lectora User Conference, it was announced that the next (or a future) release of Lectora will have a workaround for this browser limitation. By having all the content on one HTML “page” (and swapping it visibly using JavaScript), the learner will be able to tap once at the beginning of the course and then all audio will play without further user permission, transparently.

    Yay!  Any idea when this will be available?  I have 80 classes to do – all very short – but this would be so WONDERFUL!
