Can any one of you help to sort this out? My microphone produces kind of a noise which really disturbs me. I tried the mic in several ways.. using the Soun Recorder (sndrec32). It seems all my audio settings are correct. I'm suspecting it to be a hardware problem. But I dont know how to troubleshoot it. Can anyone of you instruct me how to avoid this strange noise?
The mic settings in palyaback:
- it was first set at maximum and after that I unchecked it to see whether I can hear any noise. Damn it! it does!
- Both Alternative Microphone and Microphone Boost are disable. (Indeed if I enable Microphone Boost, it increases the noise.)
About the inbuilt audio hardware:
I tried to install the device drivers using the drivers avaible in mercury-pc.com my motherborad is KOB845Gx (there are no drivers avialable for this particular motherboard thus I installed the driver set for KOB 845GL NDSMx, assuming this is it's closest matching driver set available. Apart from this, I tried few drivers from driverguide.com assuming that there might be some driver incompatibilites within the existing driver set).
I noticed a very strange thing in this system. When I installed the chipset drivers, it installed the audio controller automatically which say it's C-Madia Audio Controller(Windows XP Profession, Service Pack 2). But I uninstalled this device and tried reinstalling the driver for Intel(r) 82801DB/DBM/DA AC '97 Contoller because I saw a chip on motherboard with this number: Intel FW82802DB. I'm not sure whether this is the audio controller so I browsed the web to see what it could be, it turned out to be the audio controller for Intel Chipset of the Kob845G series motherboards from Mercury. That put me in a real confusion! I straightaway downloaded the driver and installed the respective driver from Intel for this particular controller with this id. But no luck still the microphone produces the sound!!!!
I have failed in all my attemps finally writing for an assistance from you.
I appreciate your assistance.
