Hi, I am currently experiencing a problem with the XK-VOICE-L71 firmware with HID volume control for IOS systems.
The volume step value is not "ideal".
For the iPhone 8 & iPhone X & iPhone 13 models tested so far, only when the volume of the iPhone side reaches 70%, the volume of the XMOS device output can reach the minimum sensitivity of the audio & headphones
When the volume is less than 70%, the audio or headphones (including the amplifier) connected to the IIS output will not make any sound.
When the volume gradually increases from 70% to 100%, the volume step is huge, only 5 steps are needed to reach the maximum volume.
Is there any way to improve this problem?
Technical discussions around xCORE processors (e.g. xcore-200 & xcore.ai).
