Description Kjartan Maraas 2007-08-09 11:51:22 UTC 
Description of problem:

Around line 767 the code looks like this:

        card = snd_card_get_index(str);
        free(str);
        if (card < 0)
                SNDERR("cannot find card '%s'", str);
        return card;
}

The free(str); call should be moved so it's called after finishing using str of
course :-)

Thanks for the report. I moved it to upstream and they should fix that for all
distros.

It's ALSA project bug #3300
(https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3300) and you can watch
it there.
