# AudioQueueGetParameter(_:_:_:)

Gets an audio queue parameter value.

## Declaration

```swift
func AudioQueueGetParameter(_ inAQ: AudioQueueRef, _ inParamID: AudioQueueParameterID, _ outValue: UnsafeMutablePointer<AudioQueueParameterValue>) -> OSStatus
```

## Parameters

- `inAQ`: The audio queue that you want to get a parameter value from.
- `inParamID`: The ID of the parameter whose value you want to get. In OS X v10.5, audio queues have one parameter available: kAudioQueueParam_Volume, which controls playback gain. See doc://com.apple.audiotoolbox/documentation/AudioToolbox/1552626-audio-queue-parameters
- `outValue`: On output, points to the current value of the specified parameter.

## Return Value

Return Value A result code. See Result Codes.

## Discussion

Discussion You can access the current parameter values for an audio queue at any time with this function. An audio queue parameter value is the sum of settings applied at buffer granularity, using the AudioQueueEnqueueBufferWithParameters(_:_:_:_:_:_:_:_:_:_:) function, and settings applied to the audio queue per se, using the AudioQueueSetParameter(_:_:_:) function.
