I redirected the script to a file, and this error is logged:

/usr/sbin/alsactl: set_controls:986: snd_ctl_open error: No such device

This is the code which fails, from set_controls() in
alsa-utils-1.0.7/alsactl/alsactl.c:

        sprintf(name, "hw:%d", card);
        err =3D snd_ctl_open(&handle, name, 0);
        if (err < 0) {
                error("snd_ctl_open error: %s", snd_strerror(err));
                return err;
        }

I do not understand what snd_ctl_open() does exactly.
