Squeezebox: Adjust sync per device

Feedback Feature Suggestions
1

like on logitechmediaserver, ability to adjust sync per device, in milliseconds

2

Maybe this helps;
Preferences -> Audio -> Device -> Device Setup -> Zone Grouping - Sync Adjustment (ms)

3

Sound like it might be, but I don’t even have a preferences button/menu …
Please advise. (perhaps it’s relevant - I refer to squeezebox devices here)

Aha, dunno for SB devices.
