EMU 0404 PCI sound card

Hello!
I use Ardour and QjackCdl on a 32 bit system, EMU 0404 PCI audio card with Mandriva Linux and can not record voice. Recording function works on Windows, Linux … I’m not new to Linux, but I kept all the settings in Ardour tutorial. Ardour there a sound card compatibility problem?
Thanks in advance. GVS.
