low volume Microphone

[giulio68]

hello KonstaKang, thank you for your great and great work I have tried lineage os 17.1 and 18.1 on raspberry pi4 2Gb and it works great with Gapp and 10 "usb touchscreen and HDMI audio. Great for a custom tablet, I have a single problem with the USB microphone , I clarify "with various softphone apps such as linphone, zoiper, PortSip etc. .. the audio of the microphone is low or not heard at all.

I haven't found any way to increase USB mic volume in Android's audio configs. Make sure that you've increased the USB volume level to the max because apparently this affects input volume level as well.
