I had the driver for my sound card compiled as module, i.e.:

CONFIG_SND_HDA_INTEL=m

and I did pass following options to the module (via /etc/modprobe.d/alsa-base.conf):

options snd-hda-intel enable=0,1

Now I need to have the driver "build in", i.e. not as a module:

CONFIG_SND_HDA_INTEL=y

How can I pass the options to kernel, when the driver is not a module anymore?

According to the documentation, parameters for modules which are built into the kernel need to be specified on the kernel command line with a module name prefix.

In this case add snd_hda_intel.enable=0,1 to your kernel boot line.
You can check the value of the param with:

cat /sys/module/snd_hda_intel/parameters/enable

Some parameters can be set by writing to this file under /sys, but this isn't the case for this particular parameter.
