No sound
A TREX TV Channel Has No Sound
Silent video is nearly always an audio-format mismatch. The stream is carrying an audio codec your device or soundbar will not decode, and the player passes it through anyway.

Work through these
- Check whether it is one channel or all of them
All channels silent is a device volume or output problem. One channel silent while others are fine is an audio codec on that stream.
- Switch the audio track
Many channels carry more than one audio track. Open the player’s audio menu during playback and cycle through them. On a multi-language channel this is also how you change language.
- Turn off audio passthrough
If you send audio to a soundbar or receiver over HDMI or optical, passthrough sends the raw stream to a device that may not decode it. Set the player and the TV to PCM or Stereo instead of Auto/Bitstream and retest.
- Switch the decoder
Some players decode audio and video separately. If the video decoder is set to hardware and audio is silent, try software — decoder guide.
Codecs that commonly go silent
| Audio format | Typical device that fails | What to do |
|---|---|---|
| E-AC-3 (Dolby Digital Plus) | Older Android boxes, some Enigma2 images | Set output to PCM so the player downmixes |
| AC-3 (Dolby Digital) | Phones and tablets without a Dolby licence | Choose a stereo audio track if the channel carries one |
| AAC multichannel | Some TV built-in players | Set the TV audio output to Stereo |
If a channel is silent on every device you own, including a phone on mobile data, it is the source. Send the channel name and time to support.

Sound is out of sync rather than missing.
Most players have an audio-delay slider in the playback menu. If it drifts progressively rather than sitting at a constant offset, that is a decoding problem — switch decoder.
No sound only through my soundbar.
Passthrough. Set the TV audio output to PCM. The soundbar will still work, it just receives decoded audio instead of a raw bitstream.
Can I change the commentary language?
Where a channel carries multiple audio tracks, yes — use the player’s audio track menu. Where it carries one, no.
