Linux complains a shared library doesn't exist when it really does

I'm trying to develop a plugin for alsa. I compiled my plugin as a shared library and copies it to

/usr/lib/i386-linux-gnu/alsa-lib/libasound_module_pcm_myplug.so

Then I try to test it using arecord and get the following error 

arecord --device=my_plug_test blah.pcm
ALSA lib dlmisc.c:254:(snd1_dlobj_cache_get) Cannot open shared library /usr/lib/i386-linux-gnu/alsa-lib/libasound_module_pcm_myplug.so
arecord: main:682: audio open error: No such device or address

But the file does clearly exist. I'm wondering if there is something about using .so files that i'm overlooking. Anyone have any ideas?

Could be some other dependency not found. Try:

ldd /usr/lib/i386-linux-gnu/alsa-lib/libasound_module_pcm_myplug.so

Or, is it possible your system is expecting 32-bit but you compiled 64-bit or vice versa?

Check with:uname -a
