Does iTunes sync Volume Adjustment and other per song settings?
Solution 1:
Start and stop times do sync, as well as volume adjustments.
EQ settings sync as well. However, they only work under the following conditions:
- You used a preset in iTunes (not custom EQ settings); and
- You have EQ disabled on the phone.
As backwards as that second one sounds, if you EQ enabled on the phone, it uses that EQ setting and overrides the per-song EQ settings. If you have EQ disabled on the phone, it uses the per-song EQ settings.
