Loud distorted speaker sound when connecting to power supply

Does anybody know what is causing this? It happened today after booting back to eMMC from SD. Both have the same system image flashed: Manjaro Plasma 22.08 generic

It's still happening! It disappears early after the first speaker "pop". I speculate it may be caused by a recent system update.

A somewhat similar issue happened today:

Edit: This happens after resuming from sleep (lid closed) when audio stops working, which should be related to https://forum.pine64.org/showthread.php?tid=10496. The suggested workaround

Code:

sudo tee /sys/bus/i2c/drivers/es8316/{un,}bind <<< 1-0011

doesn't help.
