AR12

I was listening to a CD the other day in my 04 Acura TL when halfway through a song the sound cut out. I could not eject, load, skip to next song, or do anything with the CD. I then switched to the radio but still no sound. I had to turn my car off/back on to get the radio sound to work again. Now every time I try to play a CD the same thing happens (no sound for anything until I restart my car). Any idea on why this is happening and how to fix it?
