Hello, please help...... I have a problem with my PC recently. When I played DVD movies, the pictures will show on the monitor, but no sound from the speaker. All system sound is normal. And I can play MP3 songs, audio CD and VCD movies, no problem. Just only the DVD having no sound. Please advice. I am using the in built Realtek ALC655 AC'97 audio in my mother board, GA-8I915MD-GV. I have installed the audio drvier recently downloaded from the gigabyte website, but still no use. Please advice, anyone. Thanks in advance.
