Variable "conf" going out of scope leaks the storage
it points to in line 856.

Simpler (untested):

   static void *oss_audio_init (void)
   {
       if (access(globconf.devpath_in, R_OK | W_OK) < 0 ||
           access(globconf.devpath_out, R_OK | W_OK) < 0) {
           return NULL;
       }
       return g_memdup(&glob_conf, sizeof(glob_conf));
   }

I think your approach is better :)
Do you want to submit a patch? Or let me post v2 for this?
