Hi,
I was previously using CentOs and there were no issues with my sound card. Recently I switched to Fedora 9 and to my surprise

the OS didn't installed the sound card. When i click on the speaker icon on the main toolbar it shows the following error,
"No volume control Gstreamer plugins and/or devices found"
I am using Intel's D945GCNL motherboard which has a built-in soundcard. Please guide me what to do and how to hear a sound from my pc.
Thanks,
Ehsan ul haq
