thanks to the help of DireFog on the ALSA IRC-channel, I verified that I
have a chip from Realtek with »ALC662« written on it [3] on my ASUS
M2V-MX SE board [2]. So in my case the correct modules are loaded.

According to DireFog (if I understood him correctly) the PCI-IDs do not
help in determining the codec since those (CODEC) chips are no PCI
devices and hooked up directly to the chipset.

Just for the record. Booting with a 686-Linux did not make any
difference.

Thanks,
