Sony USA has released a firmware update for the A17. LINK, this should work for the A15 but update at your own risk. I have not seen the update on Sony Europe's site yet.

Sony CES 2016
Another new year and another CES upon us. Not expecting anything new on the Walkman front. Perhaps Sony will introduce the ZX100 and A20 Walkmans to the US market, otherwise their press conference will/should focus on TVs, Playstation VR and perhaps photo. So far only a new speaker has been leaked or revealed, the h.ear go wireless speaker, so nothing exciting.
