Check OTT Navigator volume and audio decoding

Compare a working channel with the affected channel

Start at a comfortable volume. Record the selected output equipment, the active track and any input format shown by the television or receiver. On one working channel, identify which device responds to volume changes. Repeat on the affected channel without changing the cabling or track. A visible volume indicator and a change in audible level are separate observations.

For example, suppose the streamer’s indicator moves on both channels, but the soundbar’s level changes only when its own remote is used on the affected surround channel. Check passthrough and which device handles that signal before increasing either control further.

Try the documented one-channel choice if needed

In the eligible hardware playback route, inspect Switch codec > Use software audio decoder for that channel. Keep a note of the starting choice. Compare the same passage and the same remote after changing only this option. Check whether usable volume control returns and whether the receiver still displays the audio format you intended to keep.

If the trade-off suits just that channel, leave other channels on their existing route. For a deliberate broader change, check Settings > Player > Setup codecs preferences > Use software audio decoder. The same all-channel control can appear in Media tracks, so confirm the scope if you opened playback controls first. Compare one known working item before keeping the broader choice.

Distinguish the app fine-tune limit

Settings > Player > Sound and subtitles contains the Premium manual volume fine-tune. Simplified mode may hide it. Use it to set the app below or up to the current system volume. If the channel still behaves differently, keep the selected track, current codec, receiver format and remote that actually changed the level. Use that evidence to decide which device or app guide to consult.
