reset sound after suspend to memory (deep sleep)

[JGkn]

K, with some more modifications I was able to get the script working pretty well with sleep/resume cycles, with only caveat being applications that use sound may either quit/crash or lose sound until restart, or just pause playback - the exact behavior depends on a particular app. Here is the updated script:

Perhaps you can help me or give some hints - I can't get your solution to work.
I am on Kernel 5.7.19-1-MANJARO-ARM, coming from an installation with manjaro-arm-installer (encrypted) last week, then did

Code:

pacman -S uboot-pinebookpro-bsp
dd if=/boot/idbloader.img of=/dev/mmcblk2 seek=64 conv=notrunc
dd if=/boot/uboot.img of=/dev/mmcblk2 seek=16384 conv=notrunc
dd if=/boot/trust.img of=/dev/mmcblk2 seek=24576 conv=notrunc

and installed the above mentioned kernel via packages linux-pinebookpro (-headers), edited /etc/systemd/sleep.conf with "SuspendState=mem.

If I use your script and systemd-unit unchanged, system hangs on waking up from sleep.

If I use the command

Code:

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

directly in terminal or the echo-command for unbind in the newer script, system hangs, too (seems to start a process, that does not end and can't be aborted by strg-c.
