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 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?
