OMX_BS32 OMX_AUDIO_CONFIG_VOLUMETYPE::sVolume |
Volume linear setting in the 0..100 range, OR Volume logarithmic setting for this port. The values for volume are in mB (millibels = 1/100 dB) relative to a gain of 1 (e.g. the output is the same as the input level). Values are in mB from nMax (maximum volume) to nMin mB (typically negative). Since the volume is "voltage" and not a "power", it takes a setting of -600 mB to decrease the volume by 1/2. If a component cannot accurately set the volume to the requested value, it must set the volume to the closest value BELOW the requested value. When getting the volume setting, the current actual volume must be returned.
