Your lspci output shows that you have a Riptide combo card with HCF controllerless mode + Audio Controller + Game Controller made by Rockwell International now known as Conexant. These are frequently used in HP Pavilion PCs.
Conexant provide Linux drivers via an independant small company called Linuxant but alas these lin-modem drivers are $0 for quarter speed trial version or $15 for full speed version. You could try installing just the sound driver which I suspect is $0. For the HCF modem to function, it requires both riptide and HCF drivers installed.

After you agree to their terms you would download a generic driver cnxtinstall.run here -

They also provide the driver package in several rpm formats which doesn't help you.
Hope this helps
