Windows 7: Sound Test works, but speakers wont work

Sound Test works, but speakers wont work

The Problem:

when I do a sound test, I can hear the audio in the speakers. However when I try to play a midi file, or a DVD, the movie plays, but NO SOUND.

Usually if the sound test works, the audio plays in the speakers. So I am not sure what is happening here.


The History of the issue:


I Upgraded my emachine from Vista to Windows 7. I went to the Emachine website to update the audio drivers. The drivers that Emachine has are outdate.

I went to the Realteck website and downloaded the newest drivers.

I noticed in the device manager that their is a NVIDIA High Definition Audio, and a Realtek High Definition Audio listed.

Ok, so here is the setup.

I have a HDMI Visio TV plugged into the Emachine. Audio workes fine if I disable Realtek High Definition Audio in the device manager.

Here is the big problem: When I plug a simple set of speakers (that work on other computers) into the back of the computer, the audio will not work on the speakers.

If I enable the Realtek audio in device manger, I can get the Realteck audio options screen. Where Realtek sees that I plugged the speakers in the rear of the machine.

when I do a sound test, I can hear the audio in the speakers. However when I try to play a midi file, or a DVD, the movie plays, but NO SOUND.

Usually if the sound test works, the audio plays in the speakers. So I am not sure what is happening here.

Can anyone advise.

Ok, I found the problem, and wanted to share. I was using a VGA extension cable to connect the computer to a 55" LCD TV across the room. I noticed during trouble shooting that the left pin, on the second row of the VGA extension cable was pushed back. When I oulled the pin out, and reconnected the VGA cords, the sound worked GREAT. I have no idea what a video cord has to do with audio, but it worked. If anyone knows the teck on this issue, please shoot me the understanding. Thanks for this site!
