struggling with player

Hi Bill

Just for your interest, I used mobilePlaySoundOnChannel on an iOS app a
couple of years ago and was able to play several audio files at the same
time and change their volume while they all continued to play without

   put "word" into tChannelName
   put "now" into tType
   if the environment is "mobile" then
      if (mobileSoundOnChannel(tChannelName) is empty) OR
(mobileSoundOnChannel(tChannelName) is "could not find channel") then
         --make background audio quieter
         if mobileSoundChannelStatus("background") ="playing" then
            put mobileSoundChannelVolume("background") into tVolume
            put (tVolume - 10) into tVolume
            mobileSetSoundChannelVolume "background", tVolume
         end if
         --code to do various things like find the correct audio file
         --make changes to the GUI etc
         --play 'word' audio file
         mobilePlaySoundOnChannel tAudioPath, tChannelName, tType
         --reset GUI & background volume once sound has finished playing
         send "resetFieldBackgroundColor pField" to this stack in tMS
      end if
   end if
