Hello. Can anyone help with the Linux drivers for the speaker on the CM4Stack - i can't get the speaker to work.

The doc here describes how to use the latest OS which is 64-bit "Go to : https://t.co/3mx4cW3hqa and download the latest version." - https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/products/CM4STACK/CM4Stack Development Kit.pdf

But with that the speaker on the CM4Stack isn't there.

How could i get it to be there?
