Subject: Decibel range / value from  snd_hctl_elem_t
Date: Thu, 28 Apr 2011 20:47:05 +0200	[thread overview]
Message-ID: <4DB9B629.8090700@gmx.de> (raw)

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".
