(Original description) When adding an ARC to the hierarchy it will have an effect on the values displayed in the ARC window where the audio clip list item volume values get automatically set to the master volume value of the asset.

(New description) When saving an ARC with a lot of clips it will have an effect on the values displayed in the ARC window where the audio clip list item volume values get automatically set to the master volume value of the asset.

*Repro (new, see attached screen recording "NEW clip item volume sync")*
# Create an ARC asset
# If the audio clips list is folded, unfold it to see the volume values
# Set audio clips count to 50
# Change the master volume to some value
# Save the asset (⌘S)

Expected: Saving the asset has no effect on the displayed values of the asset

Actual: The displayed values for all audio clip list item is changed to show the same value of the master volume

*Repro (old, fixed)*
# Create an ARC asset
# Add clips to its audio clips list
# Change the master volume to some value
# Create another ARC asset
# Add clips to its audio clips list
# Select the previous ARC asset

Expected: Asset selection has no effect on the displayed values of the asset

Actual: The displayed values for all audio clip list item is changed to show the same value of the master volume

*Note*

The values shown don't affect the playback, they are only displayed wrong

Furthermore, changing the clip volume also changes the ARC volume
