Video without audio means the device is decoding the picture and refusing the sound. Almost always that is AC-3 or E-AC-3, which plenty of TVs and sticks have no licence for. The channel is fine. Your hardware is missing a codec.<\/p>\n

Change the audio track<\/h2>\n

Most channels carry several \u2014 different languages, different codecs. Open the track menu mid-playback and pick another. Sound returns? The default track was the unlicensed one.<\/p>\n

Software decoding handles AC-3 in-app<\/h2>\n

Settings \u2192 Decoder \u2192 SW. Costs a little CPU, fixes the silence. This is the standard answer on anything without a Dolby licence.<\/p>\n

PCM, not passthrough<\/h2>\n

Feeding a soundbar or receiver? Passthrough sends a bitstream the receiver may reject outright. Device sound settings \u2192 Digital output \u2192 PCM. Stereo appears immediately.<\/p>\n

Rule out the TV<\/h2>\n

Mute, a headphone plug left in a jack, a sound mode set to “dialogue”. Play a YouTube video on the same device. Silent there too? IPTV was never the problem.<\/p>\n

Corrupt audio profile<\/h2>\n

Persists across channel changes. Clear cache, not data, and relaunch.<\/p>\n

One app silent, every other app fine<\/h2>\n

Damaged install. Reinstall the current build.<\/p>\n

One channel silent everywhere<\/h2>\n

The feed lost its audio upstream. Every device, every track, same result \u2014 that is a provider fix and usually corrected within the hour. Worth a message rather than a workaround.<\/p>\n

Bluetooth<\/h2>\n

Adds 150 to 300 ms and on some sticks forces the pipeline into a low-quality profile that drops out under load. If sound only stutters on Bluetooth, that is why. Wired removes it.<\/p>\n

Which devices lack which codec<\/h2>\n

Fire TV Stick Lite, most 2019\u20132021 budget panels, and anything running a stock Android build without a Dolby licence will fail on AC-3 and E-AC-3. Samsung and LG sets from the last two years usually pass AC-3 through their own decoder and fail only on E-AC-3. A box with Kodi or VLC installed will play both, because the software decoder is bundled.<\/p>\n

What to send support if it is one channel<\/h2>\n

The channel name, the device, and whether the other tracks are silent too. That is enough for them to confirm an upstream fault without a round of questions.<\/p>\n

Plans and prices, if you are still deciding: \u05d3\u05e3 \u05d4\u05ea\u05de\u05d7\u05d5\u05e8<\/a>.<\/p>\n
