Cropped screenshots don't tell us much. Check comp settings and frame rates. Make sure you understand the After Effect user interface and preview functions by reading the help files.
If you can not figure it out please select your composition in the Project Panel so we can see the settings, select the layers that are giving you problems in the timeline and press the U key twice to reveal all modified properties, then printScreen and paste to the forum so we can see a complete screenshot. Also give us the specifications of your audio file. WAV files work best in After Effects. The standard for video production is 48KHZ 16bit PCM uncompressed stereo. MP3's are not a good idea.
Thanks for anwsering me i will add more detail screenshots when i back to home.
I tried to WAV files, but it doesn't work. WAV files played fast like MP3 files.
I will try again with re-render to WAV. I hope it works.
Anyway, i really thanks to you.
Also, please take screenshots of your audio hardware preferences.
