int UsbOutputLevel(UAC_HANDLE devHandle, float level)
Return Value
Parameters
devHandle
- The device handle of an open device. Use the value returned by UsbI2cOpen.
level
- A normalized value from 0.0 to 1.0 that represents the volume level of the output. A value of 0.0 will be minimum volume and a value of 1.0 will be maximum volume.
Remarks
Use this function to set the output volume of the audio CODEC. This sets the overall volume level of both stereo channels of the CODEC. This function, in combination with UsbOutputBalance, can be used to set the level of the left and right output channels of the CODEC.
