Playing an audio/sound with Javascript when time expires is not working on Android and IOS -

i have custom made countdowntimer in javascript shows mini seconds, seconds & minutes. can see full code below, in javascript code can assign values these variables in double digits :

var minutes = 05; var seconds = 00; var tens    = 00; 

so after assigning above values, can see 5 mins. in browser show 05:00:00. in html, have 3 buttons start, stop , reset. when press start timer start running out.

now in javascript created variable var sound , assigned audio file it. there function countdowntimer { } @ end of javascript code doing work timer, in function first if statement how know timer expired. in if statement play sound sound.play();

problem :

now of works fine on desktop on mobile devices android , ios, hear no sound when timer expired.

ideas on how play sound when timer expired on android , ios appreciated. thank you!
