Hello,
I am working on a new pcm plugin. At this point it is basically just a Hello World plugin, to make sure I have the tools working and understand the workflow. I created a simple file which is just basically:
#include <alsa/asoundlib.h> #include <alsa/pcm_external.h> SND_PCM_PLUGIN_DEFINE_FUNC(my_mod) { printf("hello world\n"); return 0; } SND_PCM_PLUGIN_SYMBOL(my_mod);
I compiled this as a shared lib named 'libasound_module_pcm_my_mod.so' and copied it to '/usr/lib/i386-linux-gnu/alsa-lib/'
I edited my ~/.asoundrc to create a new device that uses this plugin. Then I try to use it with `aplay --device=my_mod_test out.pcm`
I get the error message
ALSA lib dlmisc.c:254:(snd1_dlobj_cache_get) Cannot open shared library /usr/lib/i386-linux-gnu/alsa-lib/libasound_module_pcm_my_mod.so aplay: main:682: audio open error: No such device or address
But this file actually does exist, I just copied it there.
Any idea why this happens?
Thanks much, Brandon
