bad sound quality


I am using ubuntu edgy 6.10. My sound card is Intel AC'97.
The loudness I get in linux (ubuntu/opensuse) with master volume 80% is same as that I get in windows with volume 11%. Moreover, in windows I get very smooth sound, in linux, the sound is harsh, unpleasant. The mov files show unbearably bad (rough) sound quality, even if the same files work very fine under windows.
I give you the output of lsmod command :

I tried changing settings by alsamixer, but it didn't help me.

Can anybody help me, please?
Thanks

You could try to find out if your motherboard contains one of the C-media audio chipsets. Do some googling, or check with the motherboard manufacturer and get a spec sheet of some sort.
If you have a C-media sound device, try using that driver instead of ALSA.
I was using ALSA for my AC97 sound system with no trouble, but out of experimentation, and after discovering that I had the C-media chip, I installed the C-Media driver kernel module and have been using it ever since.
My board, for reference, is an MSI 6580 with an Intel 845PE chipset.
