Rives - I have yet to find a PCI soundcard that sounds good.
Each of these devices has different drivers and different ways of avoiding kmixer, and PCI cards usually have poor clocks, so the result is a lot of jitter.
It's hard to tell whether it jitter or kmixer that is causing your problems, probably a bit of each.
I would recommend trying to unmap the device to avoid kmixer. WMP will not recognize it anymore, but you should not be using WMP anyway if you want good sound quality. I recently tried this successfullly with a Lynx AES16. Works fine with Foobar and Jriver.
