The captions button in the player controls lists every soundtrack and subtitle the channel or film is actually carrying, with the format named beside each one. Automatic at the top hands the choice back to the stream.
The language you pick is remembered, not the track itself. Every channel change is a new stream with new tracks, so asking for Norwegian once gives you Norwegian on every channel that has it.
A track that is listed but greyed out
That means this device has no decoder for it. It is listed rather than hidden on purpose: a channel whose only soundtrack your box cannot handle used to show an empty list, leaving you with a picture, no sound and nothing on screen to explain it. Now you can at least see what it is.
A channel with a picture and no sound
Open the captions button first — it tells the two causes apart.
- The soundtrack is listed and greyed out. Your box has no decoder for that format. There is nothing to change in the app.
- The soundtrack is a surround format — Dolby Digital (AC-3), Dolby Digital Plus (E-AC-3), DTS or TrueHD. The app never decodes these itself; they are passed down the HDMI cable for your television or amplifier to handle. If that device is set to stereo, it refuses the sound and the channel goes silent with nothing to say why.
The second one is the common case, and the fix is in the television, not the app. Look for a setting usually called digital sound output or HDMI audio, and set it to pass-through (sometimes bitstream or auto) rather than PCM or stereo. Channels in ordinary stereo keep working either way, which is why only some channels go quiet.
If the sound comes back on every channel when you switch your television to pass-through, nothing was wrong with your subscription or the app — it was the box refusing a surround soundtrack it had been told not to accept.
