I have been away for a while. When I came back I had my PC with WIndows XP pro refitted with 320 Gb .My old monitor worked fine. Then for some reason, the stereo spekers inside the monitor do not produce any sounds. HAve installed the monitor driver from the CD.

When I got back my PC the sounds system says it has Sound MAX 0. IS this the problem? The monitor does not emit any sound at all.
I have looked at all sorts od possibilities in the SOUND DEVICES from XP. to no avail. Chekced Philips website also...Nothing.

Any idea anyone of what it might be.I do not want to buy speakers at this stage.
Thanks in advance to all

Short answer: the Philips 170B’s built‑in speakers need a separate analog audio feed from the PC — they aren’t driven over the VGA/DVI video cable. was pointing the right way: the Philips documentation lists a 3.5 mm “PC audio” input and even shows a lime/green 3.5 mm audio lead in the accessory pack. See the Philips user/service manual for the 170B. (documents.philips.com)

Practical steps to try (in order):

  • Look for (or buy) a male‑to‑male 3.5 mm stereo cable (Philips refers to the supplied PC audio cable as lime/green). Plug one end into the PC’s line‑out (the green rear jack) and the other into the monitor’s audio‑in. (scribd.com)
  • Power the monitor, raise the monitor volume (use the VOLUME hotkey/OSD) and make sure the monitor isn’t muted. Note: inserting headphones into the monitor’s headphone jack will mute the built‑in speakers on these models. (scribd.com)
  • In Windows XP make sure the PC’s analog output is the active/default playback device: Control Panel → Sounds, Speech and Audio Devices → Audio tab → Sound playback (set to your sound card / SoundMAX if that’s what appears). (microcenter.com)

A few quick checks and gotchas:

  • If the monitor is connected by DVI or VGA you still need the analog audio cable; DVI/VGA do not carry the PC’s audio (HDMI/DisplayPort do). ()
  • Because your Logitech speakers worked when plugged into the PC, the PC audio output is likely fine — the missing piece is getting that analog output into the monitor. If, after connecting the cable and setting the correct Windows playback device, the monitor still makes no sound, try headphones in the monitor jack (to isolate the monitor amp), verify the audio cable isn’t plugged into mic/line‑in by mistake, and reinstall the PC audio driver if needed. (scribd.com)

Is the cable for sound connected to the monitor?
Have you tried using any headphones or other speakers?

Hey, thks for taking the time.

I did not know there was a sound cable to start with.

Second, I have a pair of logitech Speakers, when plugged in worked no problems when connected to the sound outlet on the PC

The headset does work when using Skype via USB to the computer not the monitor.

Hence, it seems that I do not know how the monitor Stereo speakers can work and that is what I would like to understand and solve.
Also there is a volume control on the monitor.
Cheers

You should have a cable that will connect the monitor speakers with your PC. The cable is usually a light pale green. Connect the monitor by pluging one end into the monitor and the other into the PC; the socket should also be a light pale green at the back of the computer.

Both ends of this cable should be the same, and the ends should look the same as the one from the speakers.
