[alsa-devel] Decibel range / value from snd_hctl_elem_t

Hello list

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

In the "Simple Mixer Interface" there are
snd_mixer_selem_get_playback_dB_range and

But I can't find anything like that in the
"High level Control Interface".

Possibly related: What does TLV stand for?
