This bug still affects Debian alsa so maybe it should be merged into the main alsa. It was a problem until there was a kernel update and now the mic "just works" on newer kernels but the speaker is not working. alsamixer does see the card and when you select it you get "cannot load mixer controls: Invalid argument". apaly doesn't see it for some reason:
