tracks playing twice on top of each other
I have the strangest problem with iTunes. Until recently the player has worked perfectly. Suddenly when I play a music track now, the music will start and then a couple of seconds later it starts again, playing over the first instance of the track playing. i.e. I have 2 instances of the same track playing at once, with a delay of a couple of seconds between the 2. If I navigate to my music folder outside of iTunes and play the track, it plays perfectly.
I have deleted the iTunes app from the computer and downloaded an older version but it still the same, so there must be a problem on my Mac.
Can anyone give me some advice as to stop 2 instances of the same track playing at once? I am running iTunes 12.2.2.25 on a Mac OS X Yosemite Ver. 10.10.5.
Many thanks in advance.
