Hello all,

I have a windows XP SP2 and on board sound chip C-Media CMI9761A. Now I have a microphone, but the sound I get in sound recorder or in the speakears it's too low. I tried with other microphone and it's the same.

In sound properties I have the microphone volume at the maximum and the 'boost microphone' option selected.

My mother board is Asrock 775V88+ with Pentium 4.

The version of the audio driver is 5.12.01.0050.1 (70).

The microphone is integrated in the lcd display, Viewsonic VX2255.

Can you help in some way.

Thank you.

raised the low-mic-level problem while suggested cross‑testing on another machine and pointed toward hardware/software upgrades. Before replacing parts, run a few targeted checks that quickly isolate whether this is a wiring/connection issue, a software setting, or a missing mic preamp.

  • Confirm how the monitor’s microphone is actually connected to the PC: some monitors send mic audio over USB (or over an internal cable) rather than the analog speaker lead. Check the monitor manual for the mic wiring so the PC is definitely receiving the mic signal.
  • Verify the recording input in the OS: the correct capture device must be selected and set as default. Also check the device’s Properties/Advanced sample rate and the Levels tab (not just speaker output).
  • Inspect connectors: make sure the mic is on a mic‑input, not a line‑in. TRRS headset plugs and modern phone headsets often don’t map to PC jacks correctly and give very low or no level.
  • Bypass the onboard preamp: try a cheap USB audio adapter or a USB microphone. If levels rise, the onboard mic preamp (or wiring) is the root cause.
  • Look in the driver/control panel for enhancements (automatic gain control, noise suppression) and try disabling them; these can reduce perceived loudness or clamp levels.
  • Record a short sample with a recorder that shows peak/RMS meters to compare results between tests.

Why this happens: small built‑in mics are mic‑level devices that need bias voltage and a preamp. If the PC input expects line‑level or the mic wiring isn’t providing bias, recorded levels will be weak. If diagnostics show a hardware limitation, a low‑cost USB sound adapter or USB mic is the simplest fix; a full internal sound card is another option but not always necessary.

hi
does the microphone actually play @ a higher volume when you try it in a different pc
??

Hello,

In fact I don't know. I don't have another PC to try and, like the microphone are built in the display, isn't practicle to transport it.

I'm not a computer specialist but in my opinion the problem are in the fact of the audio chip don't have enought amplification.

If I connect a pair of speakers (someones that have AC power suply) I have a high volume. If I connect the built in speakers of the lcd display, I have a low volume.

So, I suppose that the microphone and speakers of the lcd display aren't amplified. And the audio chip of the PC don't have enought amplification for non amplified devices.

What you think about?

its difficult to say but bare in mind it is smaller speakers that will produce much "smaller" sound.but unless it played @ higher volume before

i think you are right on the money,junk plays like junk.
a nice pci sound card and a real set of speakers and mic are in order if you want quality sound, also windows sound recorder sucks ,you need a good program to do that .
sound recored program .
