[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, snd_mixer_selem_get_capture_dB, snd_mixer_selem_get_playback_dB_range and snd_mixer_selem_get_capture_dB_range

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