Ok
After a lot tried, I've finished to find what's the problem is.
For all people who have the same problem, check that your sampling frequency is in 44100 Hz (I don't seen anywhere this information but tried,...) chrome for computer has support more frequencies but default's android browser and chrome mobile does'nt support higher frequency.
I hope that my experience will be used for someone else.
thanks at all who have seen this message (I'm on this bug from more than 3 days)
