[Voyage-linux] Compiling kernel with original config from /boot not compiling same modules

[Muffinman]

Howdy all,

I've compiled a few kernels for Voyage-MPD 0.7.5 the past week and there
persists an issue with the sound kernel modules. In the new kernel some
modules are missing, such as: snd_seq, snd_rawmidi, a.o. They are not
started at boot and when I try to start them manually it says the module
is not found. I guess this is the reason why my sound is not working
altogether running the new kernel. This corresponds with the kernel
configuration file where indeed the corresponding lines are commented
out: # CONFIG_SND_SEQUENCER, # CONFIG_SND_RAWMIDI_SEQ, a.o.

The interesting thing is, I thought the file config-2.6.38-voyage
corresponded to the configuration of the precompiled  kernel supplied
with the Voyage-MPD package. However, running the original kernel, the
mentioned modules are present and added to the kernel. Also sound is
working fine. However, compiling a new kernel using an unchanged copy of
config-2.6.38-voyage (or config-2.6.38-voyage_9.0-1 from the
voyage.hk/download website) the modules are not present. This leads me
to believe that the config file does not entirely correspond the
configuration of the precompiled kernel supplied with the Voyage-MPD
package.

Assuming my reasoning is correct, my question is: where can I find the
kernel configuration file that does correspond to the configuration of
the precompiled kernel of Voyage-MPD (or a list of the differences)?

Kind regards, Maarten
