This structure is not defined to prevent applications from
depending on its binary layout.

Do it like this:
	snd_ctl_card_info_t *info;

	error = snd_ctl_card_info_malloc(&info);
	...
	snd_ctl_card_info(handle, &info);
	...
	snd_ctl_card_info_free(info);

or use alloca instead of malloc/free.

Clemens
