A picture with no sound, or sound in the wrong language, is one of the most common IPTV questions. In most cases the cause is an audio format your equipment cannot decode, the wrong output setting, or an audio track that needs switching in the player. This guide works through the fixes from quickest to most involved.
- Check mute, volume and the selected output first.
- Switch the audio track in the player for wrong-language or missing audio.
- Change the device or TV audio output to PCM or Stereo to rule out format problems.
- Try hardware and software decoding in the player.
Step 1: The quick checks
It sounds obvious, but these catch a surprising number of cases:
- Check the TV, soundbar and player are not muted.
- Make sure the TV is sending sound to the right place: TV speakers, soundbar or receiver.
- Check whether Bluetooth headphones are still connected to the streaming device.
- Try another channel and another app. If every app is silent, the issue is the device or audio setup, not the stream.
Step 2: Switch the audio track
Many channels and on-demand titles carry more than one audio track, for example English and Spanish, or a stereo track and a surround track. If you hear the wrong language, or nothing at all, the player may have chosen a track your equipment cannot play.
- Start playback.
- Open the player’s on-screen menu, often by pressing select, menu or down.
- Look for Audio, Audio track or a speech bubble icon.
- Choose another track and listen.
Some players let you set a preferred audio language in settings, so the right track is selected automatically each time.
Step 3: Check audio output format
Surround formats such as Dolby Digital, Dolby Digital Plus and DTS must be decoded somewhere: in the device, the TV or the soundbar. If the device sends a format the TV or soundbar cannot handle, you get silence.
On the streaming device
- Fire TV: Settings > Display & Sounds > Audio. Try setting Surround Sound to Stereo or “Best available” and Dolby Digital output to Dolby Digital rather than Plus.
- Google TV and Android TV: Settings > Display & Sound > Advanced sound settings. Try a manual format selection or “Stereo”.
- Apple TV: Settings > Video and Audio > Audio Format. Try changing from Auto to a specific format.
On the TV
Find the digital audio output setting and try PCM instead of Auto, Bitstream or Passthrough. PCM is understood by almost every soundbar and receiver. If sound returns, the problem was format compatibility.
Step 4: Change the player’s decoder
IPTV players can decode audio and video in different ways. If one channel is silent, open the player’s settings and switch between hardware and software decoding. Some players also have a separate audio passthrough option; turning it off makes the player decode audio itself, which often fixes silence on soundbars that lack a format.
After changing a decoder setting, close the channel and open it again so the new setting takes effect. If the change fixes one channel but breaks another, check whether the player lets you set the decoder per channel rather than for the whole app.
Step 5: Check HDMI and soundbar connections
- Make sure the soundbar is plugged into the TV’s HDMI ARC or eARC port, and that ARC or eARC is enabled in the TV settings.
- Turn on HDMI-CEC (Anynet+ on Samsung, SimpLink on LG, Bravia Sync on Sony) so the TV and soundbar communicate.
- Try a different HDMI cable, or reseat both ends.
- Power everything off, then turn on the TV, the soundbar and the streaming device in that order.
Step 6: Sound cuts in and out
If audio drops briefly, especially with video freezing at the same moment, the cause is often the connection rather than audio settings. A steadier network connection usually solves it. Our guides on Wi-Fi vs Ethernet and on fixing buffering explain how.
If audio drops without picture problems, check Bluetooth connections and soundbar power-saving modes, which can switch off during quiet scenes.
Step 7: Sound is out of sync
If you have sound but it does not match the picture, that is a lip-sync issue rather than missing audio. It has its own set of fixes, including soundbar delay settings and the player’s audio offset option. Our guide to fixing IPTV lip-sync delay walks through them step by step.
Step 8: Update and reinstall
If the issue started after an update, or appears in only one player, update the app and device software, then try reinstalling the player. A different player app is also a good test: if sound works there, the first player’s settings are the cause.

Frequently asked questions
Why do I have picture but no sound on some channels?
Those channels may use an audio format your setup cannot decode, or the player picked an unsupported track. Switch the audio track, set the output to PCM or Stereo, or turn off audio passthrough in the player.
How do I change the audio language?
Open the player menu during playback and choose a different audio track. Many players also let you set a default audio language in settings.
Sound works on TV speakers but not my soundbar. Why?
The soundbar may not support the format being sent, or ARC or eARC may be off. Enable ARC or eARC and try PCM output on the TV.
Still no sound?
Message us on WhatsApp with your device, player and any soundbar you use. We will help you find the setting that brings audio back.
