Hi I think that is already fixed in the latest Ubuntu Mate images (script restores mixer settings after suspend), you can upgrade to ayufan's latest release like described here:
https://github.com/ayufan-pine64/linux-build/releases
If you loose your audio settings for some reason you can also get the original asound.state file from his repo at:
https://github.com/ayufan-pine64/linux-b...r/lib/alsa
Put that back into /var/lib/alsa and call alsactrl restore
Edit: Yes the mixer has a lot of settings exposed, that is because the audiocodec combines three interfaces into one and has a lot of paths, if you want to know more look at the usermanual for the A64 in the wiki.
The critical volume controls are AIF1 DAC timeslot 0 volume = ca. 65, DAC Volume = ca. 60 and Speaker Volume ca. 80-90 for the internal speakers.
