HiFiBerryOS64 alpha7 Initial volumelevel not read after (re)start

Describe the bug After (re)start the volumelevel stored in alsactl.store is not read.

HiFiBerryOS version System software 20240410

HiFiBerry sound card Beocreate 2.4.5

To Reproduce

Check /etc/alsactl.store DSPVolume (see below)
run "amixer" to see volumelevels
see DSPVolume from amixer output not matching the level in alsactl.store:

# amixer
Simple mixer control 'DSPVolume',0
  Capabilities: volume
  Playback channels: Front Left - Front Right
  Capture channels: Front Left - Front Right
  Limits: 0 - 255
  Front Left: 252 [99%] [-2.00dB]
  Front Right: 252 [99%] [-2.00dB]
Simple mixer control 'Softvol',0
  Capabilities: volume
  Playback channels: Front Left - Front Right
  Capture channels: Front Left - Front Right
  Limits: 0 - 255
  Front Left: 255 [100%] [-0.95dB]
  Front Right: 255 [100%] [-0.95dB]

Expected behavior In the previous version 20230404 the level in alsactl.store is used as the initial volumelevel. In the current version the level is 252, almost 100%. This is way too loud.

Additional context /etc/alsactl.store:

state.sndrpihifiberry {
    control.1 {
        iface MIXER
        name Softvol
        value.0 123
        value.1 123
        comment {
            access 'read write user'
            type INTEGER
            count 2
            range '0 - 255'
