Hi,

Having a problem with sound. Actually, am not getting any sound at all. When i try inserting my speakers or headphones am only getting static and absolutely no sound. Have a Intel 845GVAD2 M/B with integrated sound using SigmaTel Audio Codecs. Any help would be appreciated as this is driving me mad!!!:sad:

OP described static-only output from the onboard SigmaTel codec on an older Intel 845 board. Static with both speakers and headphones usually points to one of three things: driver or mixer/output-selection problems, a bad analog output/front-panel jack, or power/ground noise or failing onboard audio hardware. 's suggestion to get the correct driver is the right first move, and 's PSU check is also sensible if noise or other device instability is present.

Recommended quick checklist:

  1. Verify the speakers/headphones on another system to rule them out.
  2. In the OS Device Manager, uninstall the audio device, reboot, then install the vendor-supplied audio driver (avoid random driver sites).
  3. Confirm the audio service is running and the mixer is not muted; check whether output is accidentally set to a digital/SPDIF device.
  4. In BIOS, ensure onboard audio is enabled and any SPDIF/analog options are set correctly.
  5. Disconnect the front-panel audio header and test the rear line-out to exclude a bad front jack or wiring.
  6. Boot from a clean live USB/CD to separate OS/driver problems from hardware faults.
  7. Try an inexpensive USB audio adapter or PCI sound card; if that fixes it, the onboard codec or nearby power components are suspect.

If problems persist, visually inspect the motherboard for bulging/leaking capacitors near the audio area and consider PSU swap or testing (intermittent device failures like those mentioned by often implicate power or the motherboard). Replacing the motherboard is a last resort; a cheap USB sound dongle is a practical, low-cost workaround. Caution: flashing BIOS or installing chipset drivers can cause other issues—back up data first.

Hi,

Hi

I have PC with 1.7 Ghz, and Intel 845GVAD2 M/B. I face problems of not detecting hard drive, cd room, and LAN card. Such problems occur daily and I cure them by pluging/unpluging the device and cables.

  • I want to confirm wether It is the problem on mother's hand?
  • I am thinking to change the mother board. Will it work?
  • If I change the mother board, should I have to change Processor?

Thanking in anticipation.

Regards,
Shah
