No Audio: No other option left?

Hi,

I have AMD based K8N Diamond MB with Creative sound Blaster Live 24-bit onboard audio

Everything is working fine except Audio. I have tried Kalyway, Leo4all, Zephyroth 10.5.2 Leopard AMD. Results are same. Is there any other option for me except replacing the MB with Realtek/AC97? Kindly let me know if there is any external card compatible with above Leopard versions.

Any help will be appreciated. If I resolve this sound issue, I will be dumping windows for good.

Regards,
AG
