after last update when I load Sfizz or LinuxSampler and I load a soundfont the volume is almost zero even if volume indicators show normal volume.  
hardware is Zynthian V4

PS  
I realized this happens using my snapshots.  
If I create a new snapshot the volume is normal.  
This means that all my snapshots cannot be used 😬  
I attach a snapshot that has this issue.

I discovered that after loading old snapshots (surely with Sfizz but also others do the same) the general output levels are set to 11.

Any idea?

Maybe a tribute to Spinal Tap, in reference to the new movie??? (Although the trailer shows it now goes up to ∞.)

It could be but I would like to avoid it

Is the volume control set to 11 or is the sfz opcode set to 11, or something else?

It happens systematically: I load a snapshot and I found that the general output level (the one under admin voice of menu) is set to 11.  
I set it to 80 and after loading another snapshot is another time set to 11.

Clear the MIDI learn it might be getting a volume CC from somewhere.

After flashing SD and updating, many of my snapshots (using SFIZZ LINUXsampler Aeolus setBfree) have this problem:  
after loading the snapshot the MAIN Audio Levels right and left are set to 11  
MIDI seems not the cause.  
I revised all adjusting MAIN Audio Levels and saving: not a big problem but only boring.
