avrcp volume control

[AvishkaDon]

Hi,

I was wondering if the BluetoothA2DPSink::set_volume(uint8_t volume) function set the absolute volume? (i.e when I change the volume on the esp32 the volume slider changes on the source device). I've been trying to get it working but it doesn't seem to work for me and I am not sure if I am using the correct function for this.

I came across this and I believe this is a similar issue as I am having: #41

Many thanks 🙏

Can you double check the Arduino ESP32 Version. You need to use a version > 2. The latest version is 2.0.2.
If you use this version and it is still not working then your phone might not support this function. In this case the set_volume() function is just applied on top of the volume provided by the phone...
