Is one title silent, or is every Netflix title silent?
Try another title on the same device, then compare a non-5.1 audio track where available. If stereo restores sound, investigate the surround-sound path. If another app is silent too, check the device's selected output and speaker setup. Browser playback also has separate player, tab and computer volume controls.
Applies to: Netflix video playback on TVs, TV-connected players, computer browsers and mobile devices. Audio formats depend on the title, language, device and connected equipment.
Where does the sound disappear?
Keep the test focused on video that is actually playing. A black screen with no audio belongs to the black-screen guide. Here, compare titles, audio tracks and outputs so a working part of the setup stays out of the repair.

Compare the output path1. Compare a second title and the selected track
Play a second Netflix title on the same device. Our recommendation is to keep the volume and output unchanged for this comparison. If only the original title fails, note its episode, language and the point where audio disappears.
Netflix's reporting workflow accepts audio and dubbing issues. In a browser, open Account > Profiles > the relevant profile > Viewing activity, find the title and choose Report a Problem. Continue the device checks if every title is silent.
2. Use stereo to test the surround-sound path
Open the playing title's Audio & Subtitles controls and choose an available audio option without 5.1. On computers or mobile devices, tap or click the picture to reveal controls; on TV devices, use the remote's up or down arrow.
Netflix's no-sound guidance uses a stereo comparison on applicable TV-connected devices. If that restores audio, keep the result as evidence for the equipment manufacturer. It points to a format or setup problem needing investigation rather than proving a speaker is broken.
Netflix says 5.1 requires support from the title, streaming device and audio equipment. Availability also varies by language, and downloaded titles do not provide 5.1. For surround playback, check the title's 5.1 label and the device's compatible output setting instead of assuming every audio track uses the same format.
3. Browser or mobile: check the controls for media
For computer playback, check the Netflix player's volume, whether the browser tab is muted, and the computer's volume. On Android, adjust media volume while a title is playing. These are separate controls; an audible notification does not test the movie's audio level.
Our next comparison is the built-in output versus connected headphones or speakers. Note which path is silent before changing devices or restarting apps. Once sound returns, reduce the volume to a comfortable level before reconnecting the original output.
4. TV equipment: compare the normal output with the external system
Check the HDMI or optical connections and speaker wiring for the actual setup. Netflix specifically suggests disconnecting an external audio system for Roku and Xiaomi devices and testing the default output. On other products, use the manufacturer's documented output-selection procedure.
Our diagnostic recommendation is to compare another app through the same output. If every app is silent there, continue with the TV or streaming-device audio guide linked below. If only Netflix fails, retain the title and stereo comparison results when contacting support.
For assistive listening or voice-clarifying equipment, Netflix notes that Stereo or Linear PCM output may be required. Ask the equipment or streaming-device manufacturer for the correct setting. Do not copy a console menu path onto a different player.
Frequently asked questions
Why does stereo play while 5.1 has no sound?
The comparison narrows the fault to the surround-sound setup or format handling. Netflix requires compatible title, device and audio equipment for 5.1; check the equipment's documented output settings.
What if only one film has no sound?
Compare another track if available and report the affected title through Viewing activity. Include the language and playback position so the report describes the specific failure.
Should I reset the TV when Netflix is silent?
First compare another title, a stereo track and another app through the same output. Those results determine whether to investigate Netflix playback or the device's wider audio setup.
