I have a problem here and I'm hoping someone can help me out. I just inherited a IBM Thinkpad A31. It was used in an office and I was told I could have it as long as I formatted the hard drive before using it. I performed a clean install using an XP disc. The system installed most of the driver automatically, including recognizing the sound card as an Intel audio device. At this point, the sound did not work, so I ran Windows Updates, and it updated the audio drive to a SoundMax audio device. The sound still didn't work. So I uninstalled all audio drivers and reinstalled it manually. Still no sound. I also ran the dxdiag test. It said everything was working and I should be hearing music, but there was no sound. This is also the case when headphones are plugged in. No sound. So I plugged a microphone into the microphone jack, thinking the sound card might be bad, but the microphone works. Any recording program on the computer, sound recorder, the dxdiag test, and the soundmax control panel shows noise activity (though I can't hear it).

I also looked in the BIOS for any audio options, but there are no audio options in the BIOS.

Does anyone have any suggestions? I am no dummy when it comes to computers, so any help on this odd problem would be great. It does not make any sense to me, and I have search for a similar problem but have yet to find it.

The only thing I can think of is if the company who owned the computer before me somehow disabled any sound output but damaging the onboard sound card on purpose.

Can anyone help?

I played around with it, and did some more searching and finally found out what the problem was. The volume buttons on the notebook, above the f1, f2, f3, f4, buttons, work, but they are for the output sound only, so hitting the volume up and down buttons will not affect the slider in the windows volume control. it was set to mute on reformat, and i had to hold the volume up button all the way for a few seconds. Nothing change on the screen and nothing was noticed, but i guess it raised the output sound, and then i had volume. simple fix. i thought it was something internal and major and i almost bought pcmia sound card. good thing i didnt.
