Description:

The snd_mixer_element_volume1_range structure describes the range of the volume element. The members include:

min

The minimum volume increments.

maxium

The maximum volume increments.

min_dB

The minimum decibel (dB) range value that's multiplied by the dB_scale_factor.

min_dB

The maximum decibel (dB) range value that's multiplied by the dB_scale_factor.

db_scale_factor

The value by which min_dB and max_dB have been scaled.
