Only popping noises come out of extra speakers connected to my ViewSonic monitor. How do I fix this?

It should with the vga cable it will be a small rca audio plug

Please clarify what type of pop noise. Audio pop or just a pop noise and the unit may no longer be working?

I was having this same problem with my monitor for days and it was driving me nuts, and being in IT not being able to solve it was even worse. My Viewsonic is a VA2232wm with built in speakers, I muted the speakers on the computer and using the control buttons on the monitor with no luck, it was still clicking. I move my laptop to and from my desk all the time and everything goes to the monitor via a USB docking station except for the audio. The audio cable I have to plug in separately. In my haste, the last time I connected the audio cable to my laptop, I put it in the microphone jack instead of the speaker jack. Once I moved it to the right jack, the problem was solved. Not sure if this will resolve your problem or not, but I hope it helps.

Try the above link for Vista or XP drivers which may be used with Windows 7 in some cases.

The va1912wb came up when I searched under 1912.

This driver is available directly from the viewsonic.com site.

Uninstall the other driver if possible.

your monitor have 4 buttons in the right down. the first is for turn on or off the speakers ;)

You need to plug the 3.55mm audio cable on to the computer (usually the green line-in) and on to your monitor's audio line in. Hope this helps.

I brought pc with ViewSonic VA1912wb 19" LCD it have in built speakers or not how i connect get suond with out externals speakers

If your monitor have inbuilt speaker, then you need not to plug it, because the monitor cable will work for that. I have ViewSonic 19" with inbuilt speaker and its working without any extra cable or connection.

turns out it may be a heating problem. cut a few extra vent holes in it and seems to be fine.
