How have you connected the audio cables to the TV? The 3250HD has component, DVI, and composite video out. There is also two analog audio outputs (for the component and composite video) and a digital audio output. Make sure that you are using a TV and not a monitor. Many monitors do not have built-in speakers. (In that case, use external speakers.)
If you use the digital audio output, make sure that your audio receiver audio input is connected to the set top box audio out. Then make sure to set the correct source for that audio signal. (Note the TV may have a digital audio port; that is an audio out.)
If you are using one of the analog audio outputs directly to the TV, make sure that you are using the correct set of audio IN on the TV and audio out on the set top box. (If you are on the Component input, your audio won't be heard if you are using the Composite audio output.)
Next try different audio cables. Make sure that the TV speakers are on. (Some TVs have an option to disable the speakers if you use external speakers at times.) Try connecting the audio output to a receiver and speaker system (or speakers with aux in). You might need an RCA F/F to 3.5 mm M adapter for some devices. If another set of speakers do not work, then the set-top box probably has a broken audio output. If another set of speakers work, then the problem is with the TV audio. This could be a problem with the jack or the speakers.
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.
Cindy Wells (I have had the speakers fail in monitors; <$30 separate speakers are an adequate replacement for those built into a flat panel monitor.)
The HDMI audio should be controlled by the video driver. You may need to change the audio output to get the TV speakers to get the audio from the HDMI signal. Open the Control Panel (Start > Control Panel with Windows 7 and Vista) and go to the Hardware section. Find the Sound section and click on the Manage Audio Devices link. In the Playback tab, right click on HDMI Output and try to make it the Default audio device. If you see a test option, check if you hear the audio from the TV speakers.
For laptops, the usual default audio is the built-in speakers.
Hi, Philips 190X6
LCD Monitor has built-in Speakers but no microphone.So, you can connect the LCD to the PC output but for Mic the option is that you may buy a separate Mic. PRODUCT GUIDE (REFER TO PAGE21)
Hope it helps! Good Luck! Thanks for using Fixya! CreativeTECH
If your monitor has speakers built in, it's likely that there is an Audio Out port on the back or one of the sides. You can use a simple 1/8" input/output cable that will connect to the port on your monitor and the Audio In port on your desktop.
If you already have that set up correctly and you are still not hearing any audio coming from the monitor, there may be a configuration console that is available after installing the software for the monitor. If you don't see any software installed, find the installation disc and see if there is an application available to install.
If you don't have the disc, you might be able to find the software online at the manufacturer's support site.
You might also be able to change some configuration settings from within the Sounds and Audio Devices console in Control Panel.
Assuming your using a Windows operating system, you need to got to the sound settings and set your computers soundcard as the preferred output device. (Its under Control Panel > Sounds and Audio Devices in XP)
Did you run the audio cable from the computer to the monitor. If not you must have that for the speakers to work. If yes can you verify computer output with another pair of speakers to narrow it down to computer or monitor. If it is the monitor built in speakers that are the problem reply and we can go through a procedure to get them working.
