Correctly handle USB Speakers with piCorePlayer (6.0.0)?

Hello!

I have a piCorePlayer 6 installation with LMS and to use it also as a headless player I attached USB Harmon Kardon Soundsticks to it.
To get good results for volume I had to use alsamixer:


I saved it using the website:


If I am not using alsamixer the music is nearly off at 50% volume setting, it is at normal hearing volume when I use 85% volume setting. At 100% is is a little bit louder. This is a very strange setting, so I used alsamixer to use the whole volume control and not only a part of it.

Because I not always use the Soundsticks, I am switching them off. But after switching them back on the values for alsamixer are switched to this:


If I am doing a restart of squeezelite then, nothing changes. The value for alsamixer is not restored.
Also if I am doing a reboot of the whole Pi nothing is restored.

What do I have to do to get the alsamixer value back after switching on the speakers and after a reboot?

This are the values I used on the squeezelite page:
Audio output device settings: USB audio
Output settings: hw:CARD=SoundSticks,DEV=0
These are the possible values there:


ALSA setting: 80-4--1-

What do I have to do to handle this correctly? What I am doing wrong?
