I'm stuck with the hctl interface. What is the best way to get

1. the decibel range from a snd_hctl_elem_t
2. the decibel value from a snd_hctl_elem_t

The hctl stuff is just a thin wrapper over the ctl stuff, so call snd_hctl_ctl and snd_hctl_elem_get_id, then snd_ctl_*dB*.

Yes; but you should let alsa-lib parse it.
