42PFL7676H does not send sound from '3D from USB' to optical out
I have a 42PFL7676H (as I mentioned before) and I want to play 3D movies from USB.
After some experimenting I got that working (found out that the TV is quite picky when it comes to sound and video-formats), but now my MKV's work, with audio AC3.
I have an old amplifier and I have bought an optical-to-electrical converter, to connect the TV to it. That works like a charm, when watching TV or streaming from my PC. However, when I play 3D from USB, the sound only plays on the TV speakers (no sound on optical out).
Can this be a bug? Or is it something I'm missing...
