I have a 64-bit operating system: Vista Service Pack 2 (two). The monitor is an HP w2207h HDMI with internal speakers.
When I play a dvd with audio going to the monitor speakers, I get this nasty repeating rumbling noise that has both a low-pitched and a high-pitched component to it; absolutely no intelligible audio (music, dialog, etc.) comes through, and the video displays fine. However, when I play the dvd using headphones, there's no problem with the audio whatsoever. There are no other problems related to audio coming through the monitor. I control whether the audio goes to the headphones by using the "Realtek HD Audio Manager" found in the Control Panel; when I choose "Speakers," the audio goes to the headphones; when I choose "HDMI Output," it goes to the monitor's internal speakers.
Any assistance with this vexing problem would be greatly appreciated. Thank you.
