Microphone problem in Fedora Core 3(Intel 915GVWB Motherboard)

[Manilal K M]

hello all,
  I have just installed the FC-3 in my new intel D915GVWB motherboard.
Initially I noticed that the sound card is not working. Then I
upgraded the alsa package and the kernel and got the soundcard
working. Now its seen that the microphone is not working properly.
When I run "gnome-sound-recorder", it hangs up. I tried audacity also.
still in vain. can anyone suggest any method to make my microphone
work.
The dmesg shows that the system uses "obsolete OSS audio interface"
The details of the device is as follows:
Sound card:
[root at gamma ~]# cat /proc/asound/cards
0 [Intel          ]: HDA-Intel - HDA Intel
                     HDA Intel at 0x501c0000 irq 193
The output of the dmesg :
ACPI: PCI Interrupt 0000:00:02.0[A] -> GSI 16 (level, low) -> IRQ 193
[drm] Initialized i915 1.1.0 20040405 on minor 0:
