Hello! 
 I have a problem installing my soundcard on fedora core 6 (PC, AMD
 Sempron 2800+, AsRock AM2NF6G-VSTA - motherboard) .
 
 The PCI Audio is nVidia Corporation MCP61 High Definition Audio and the
 kernel that i just installed is 2.6.18.3
 
 I have installed the alsa driver (version 1.0.13), the library and the
 utilities (the same version) just like is indicated on your
 documentation.
 
 I have created the snd devices and chmod them.
 
 I have compiled and installed the alsa driver using the following
 configure command options: 
    ./configure --with-cards=intel8x0 --with-sequencer=yes;make;make
 install  
 
 After everything was successfully installed i have loaded the modules
 into the kernel like this:
 modprobe snd-intel8x0;modprobe snd-pcm-oss;modprobe
 snd-mixer-oss;modprobe snd-seq-oss
 
 The lsmod command shows this:

 snd_page_alloc         14344  2 snd_intel8x0,snd_pcm
 
 I got no error and no card is being detected at this stage
 in /proc/asound/cards

 And the details for the sound card (lspci again):

 The alsaconf command says no sound card could be detected on my system,
 which seems to be true as /proc/asound has no reference to the sound
 card.
 
 I need a little help please! I will wait for an answer on this email
 address.
