Hi all,
I want to leave OS handle volume and mute of my virtual speaker. I tried to change KSPROPERTY_AUDIO_VOLUMELEVEL to null, but I have some problem.
- Mute button of virtual speaker not work.
- Maximum of output audio is the value of the system volume at the time of swtiching to virtual speaker. Example, I set system volume to 10, then switch to virtual speaker. At this time, value volume of virtual speaker is 100. When I change value volume of virtual speaker from 0 to 100, the output audio volume change from 0 to 10, and sounds very small.
Thanks in advance
