Property HeadSetVolume As Long
Read/Write: Read and Write


Sets/returns the phone HeadSet earphone volume.


The HeadSetVolume property specifies the earphone volume level of the HeadSet phone device. This is a number in the range 0 (silence) to 65535 (maximum volume). The actual granularity and quantization of gain settings in this range are service provider-specific. A value that is out of range is set to the nearest value in the range.

You should test the HeadSetCaps property to discover if the phone device supports volume control.
