Hello wizards.
I recently reformatted my HP-Pavillion 7845 computer with a new Windows ME operating system. Like many others in this forum, my sound will not work. No microphone icon appears in the taskbar, everything is grayed out in the audio tab under multimedia settings in the control panel, etc. etc. I believe I have an onboard sound card because before the reformatting, I controlled the volume by a button on my keyboard and I know for a fact I have never physically installed any sound card.
Under the control panel\system\device manager every little box has a + sign to the left of it EXCEPT 'Sound, video, and game controllers.' My Crystal WDM Audio Codec tells me that the device is working properly, and my computer has 4 driver files:
C:\WINDOWS\OPTIONS\CABS\cwawdm.sys
C:\WINDOWS\SYSTEM\VMM32.VXD (ntkern.vxd)
C:\WINDOWS\SYSTEM\MMDEVLDR.VXD
C:\WINDOWS\SYSTEM32\DRIVERS\CWAWDM.SYS
The provider, file version, and copyright info is available for each file except the C:\WINDOWS\SYSTEM\VMM32.VXD (ntkern.vxd), which simply says 'unavailable.'
I checked programs/accessories/system tools/system information/components/multimedia/sound device, and I get:
Name Crystal WDM Audio Codec
Manufacturer Crystal Semiconductor Corporation
Status OK
IRQ Channel IRQ 9
I/O Port 0x1200-0x12FF
I/O Port 0x1300-0x133F

Driver c:\windows\system\mmdevldr.vxd (4.90.3000, 17.62 KB (18,043 bytes), Not Available)
I hope this is enough information to warrant any help you may be able to provide. Thanks in advance.
