Parameters

streamType
Stream

stream type for which the volume is queried.

index
Int32

the volume index for which the volume is queried. The index value must be between the minimum and maximum index values for the given stream type (see #getStreamMinVolume(int) and #getStreamMaxVolume(int)).

deviceType
Int32

the type of audio output device for which volume is queried.

Returns

a volume expressed in dB. A negative value indicates the audio signal is attenuated. A typical maximum value at the maximum volume index is 0 dB (no attenuation nor amplification). Muting is reflected by a value of Float#NEGATIVE_INFINITY.
