A quick lambda call to disable all instances' detailed monitoring. Can be scheduled with CloudWatch.
const AWS = require('aws-sdk');
const ec2 = new AWS.EC2();
exports.handler = async (event) => {
let ret = await ec2.describeInstanceStatus({}).promise();
const instances = ret.InstanceStatuses.map(a => a.InstanceId);
const param = {
InstanceIds: instances,
};
ret = await ec2.unmonitorInstances(param).promise();

simple lambda to update all container instances, could be triggered by cloudwatch rules
const AWS = require('aws-sdk');
const ecs = new AWS.ECS();
exports.handler = async (event) => {
const clusters = ['your-cluster-name'];
for (let cluster of clusters){
const data = await ecs.listContainerInstances({cluster}).promise();
for (let cid of data.containerInstanceArns){
let result = await ecs.updateContainerAgent({cluster, containerInstance: cid}).promise();

Make customized wm8731 work on RPi 3
  1. edit /boot/config.txt and comment out dtparam=audio=on, remove comment for dtparam=i2s=on, dtparam=i2c_arm=on. Add dtoverlay=audioinjector-wm8731-audio
  2. Add snd_soc_wm8731 in /etc/modules
  3. Set GPIO25=1 (turn on audio Amp. Should turn off when Audio is not used)
  4. Turn on Output Mixer HiFi (https://github.com/raspberrypi/linux/blob/rpi-4.14.y/sound/soc/codecs/wm8731.c#L187) in amixer for speaker. Use speaker-test to verify. Volume is controled by Master (https://github.com/raspberrypi/linux/blob/rpi-4.14.y/sound/soc/codecs/wm8731.c#L161) 5 Turn on Mic (https://github.com/raspberrypi/linux/blob/rpi-4.14.y/sound/soc/codecs/wm8731.c#L171) and switch Input Mux to Mic in amixer.(https://github.com/raspberrypi/linux/blob/rpi-4.14.y/sound/soc/codecs/wm8731.c#L206) Test with arecord and aplay
