android app starts playing after ending a phone call...

[gearson]

... even if the app was not playing before the call started.

Subsonic server 4.7 (build 3105) running on mac os x server 10.8.2
Subsonic client 3.4 running on a Razr Maxx w/ ICS 4.0.4.
The phone is connected to a Kenwood KDC-X996 via bluetooth.
Please help, and thanks in advance.
