gistfile1.txt

# This are the command line commands to change the bluetooth settings in case of audio stuttering
# Changes are based on the nice video made by Simon McCabe on youtube where he is using the bluetooth explorer app
# https://www.youtube.com/watch?v=OVRbLRRz5TU
# The settings are reversible but proceed at your own risk.
# 
# My defaults are
#  sudo defaults read com.apple.BluetoothAudioAgent
# {
#     "Apple Bitpool Max (editable)" = 64;
#     "Apple Bitpool Min (editable)" = 50;
#     "Apple Initial Bitpool (editable)" = 40;
#     "Negotiated Bitpool" = 40;
#     "Negotiated Bitpool Max" = 53;
#     "Negotiated Bitpool Min" = 2;
#     "Stream - Flush Ring on Packet Drop (editable)" = 0;
#     "Stream - Max Outstanding Packets (editable)" = 30;
#     "Stream Resume Delay" = "0.75";
# }

# Check the default values
sudo defaults read bluetoothaudiod
sudo defaults read com.apple.BluetoothAudioAgent

# Changes to fix the stutter

sudo defaults write bluetoothaudiod "Enable AAC codec" -bool false
