I am using the respeaker HAT on my raspberrypi 3. After installing the drivers im able to record the sounds using the inbuilt mic and play it from my speakers (using the command arecord -f cd -Dhw:1 | aplay -Dhw:1). But when im trying to use voip using this everything is working fine but the sound from the mic heard on my another device (softphone installed on android) is heavily distorted. but when im recording the sound through the mic on respeaker and when I play it through the speakers connected to respeaker it comes out fine. I would be a great help if someday could help me out with this. thanks in advance
