RTL XL app, sometimes no sound through spdif out

[rollufje]

Hi all,

Sometimes when starting a video via the RTL XL app (holland) I don't get sound through spdif.
When I turn on the internal TV speakers I do get sound.

It seems only to occur when there's a comercial video added before the video. The sound of the commercial does work, the sound after that fails.
When I start the video again, and there's no commercial the sound output does work.

App: RTL XL

Greets,
