Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

We were able to replicate the lack of audio on the launcher itself and are currently looking into that.

As for the install size, I'd like you to verify something. Can you check the storage option in the Settings menu of the PS4 and find Final Fantasy XIV. Then click the Options button on the FFXIV icon on the Home Screen and select 'Information.' Both of these should give you the install size, is there any discrepancy between them, or are they both exactly 56.21 GB?

Next, can you go back to the 'Information' screen (by clicking the Options button on the Icon from the Home Screen) and click 'View' next to 'Installed Add-ons.' What do you see here? Do you see any duplicates?

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
