I have headphones plugged into the audio plug but sound still comes out through monitor speakers. i am using the monitor to display HDMI signal from xbox 360. sound works fine from built in monitor speakers but i need to route that through headphones to keep audio form being heard by other people

Your HP Pavilion F1903 monitor does not have built-in speakers. Your desktop computer probably did not come with speakers. You will have to plug computer speakers into the audio-out jack (green) on the back of your computer to play through external speakers.

There are also a number of USB speaker systems available that use USB both for power and for the audio signal.

Alternatively, there is probably an earphone jack on the front panel of your computer. If you plug headphones into that you should be able to listen on your headphones.

Are you feeding the monitor via an HDMI connection? HDMI carries digital audio as well as digital video signals. If using DVI or VGA to connect it to your PC, there is no audio being fed to the monitor, so nothing can come out, unless you have a separate audio cable running to the monitor as well from the computer :o)

If you don't plan on using the headphones - take the cover off and there may be a cable to the headphone jack board that can be unplugged. This will disable the headphone jack from sending a bad signal to the micro. If you want to be able to use the headphone, then the jack is going to have to be replaced.

The Samsung SyncMaster P2570hd is a monitor with speakers; it isn't the computer itself. I'll assume that you are dealing with a computer connected to the monitor and not a set-top box. Make sure that Mute is not enabled on the computer. There should be an icon on the lower right hand side of a Windows desktop. If the mute is enabled, it will have a red circle with a diagonal line through it. Left click on the icon to remove the mute (change the volume or click on the mute icon). Test the monitor's speakers by connecting it to another device with known good audio output.

Next how are you connecting the monitor to the computer (VGA, DVI or HDMI)? If you are using VGA or DVI (including DVI to HDMI), you need to connect an audio patch cable (3.5 mm) between the speaker (green port on the back of a sound card) or headphone jack of the computer and the audio input jack of the monitor. The audio input jack is between the DVI and VGA ports. You can test the output of the speaker jack on the computer with regular computer speakers. Plug in the power cord (or USB cable) for powered speakers. If the free-standing speakers work, check the volume setting on the monitor with the +/- buttons to the right of the menu button. Do not press menu first, though. If that doesn't solve the problem, continue using the separate speakers. (Unless the monitor is still under warranty, it usually isn't worth taking apart a monitor to replace the speakers. You may be able find replacement parts online.)

If you are using an HDMI cable, check the output audio setting to see if the HDMI audio is available. For Windows, click on Start > Control Panel > Hardware and Sound (Windows 7). Then click on Manage Audio Devices under Sound. In the Playback tab, check what available audio devices you have. Make the HDMI the default device by right-clicking on it and selecting Make this the default device. (Other versions of Windows will a slightly different route to this panel.) You may need to restart the computer to get the audio signal on the HDMI cable after setting this. Note: not all video cards/computers support HDMI audio. If you don't see HDMI listed in the Playback devices, connect an audio patch cable as with a VGA or DVI cable, described above. Use stand-alone speakers if the monitor's speakers are bad.

I hope this helps.

(I have had the speakers fail in monitors; <$30 separate speakers are an adequate replacement for those built into a flat panel monitor.)

How do you have the screen plugged in?
If via HDMI, audio should go to your screen, but you may need to output to speakers (that is, if your monitor does not have built-in speakers).
If indeed outputting via HDMI, make sure your computer KNOWS it's supposed to output audio through the HDMI port as well as the video.
Finally, you might just need to plug speakers/headphones into the monitor - most have an audio jack on the underside, by the stand.

There is no audio output on that monitor. So decoding the HDMI into analog is out. However, the simple fix is to plug your speakers or headphones into the green 3.5mm headphone jack on the back of your computer, and change the default audio device in windows. You can use both audio cards at once for different tasks, such as having someones voice come over your HDMI cable on the monitor, while listening to music on the audio out of your computer.

If you need any help setting the audio card, let me know.

No it's not possible to have a sound. Because the HDMI and the Headphone (3.5mm jack) are on two different technologies.

The monitor does not have a way to convert the sound from HDMI to Headphone.

There could be a converter that might convert the sound signal from HDMI to headphone (but I'm not sure).

The Jack which you found nearby the HDMi is a Input jack. you can get a output from your Computer's Audio out to to this input jack the speakers integrated with the moniter make sound. here there is no chance to plug your headphone. if you want you can plug your headphone in the front jack of your computer

Dear marco1983,

there are no speakers on G2400W, just the plug hole for speakers that routes forward the sound signal from the HDMI signal.
