There is some mp3 audio in the course however it is not playing consistently. for example:
course 1 - audio works on my PC but not on my android phone, nor my colleagues android. Does work on I-phone. Published from SL1
Course 2 - audio works on my PC and on my android phone. Doesn't work on my colleagues android phone. Does work on I-phone. Published from SL2
Course 3 - the same as course 2.
Why is the audio so inconsistent? How do I fix it?
