Anki Audio Not Playing? Fix Missing or Silent Sound

If Anki audio is not playing, first determine whether the problem affects one note, one deck, or every card on the device. Then check the card's audio field, replay and autoplay settings, missing-media report, template, package contents, and media sync in that order.

That sequence matters. A silent card can come from a disabled autoplay option, an empty field, a broken [sound:...] reference, a file that was never included in the APKG, or media that has not finished syncing. Reinstalling Anki will not repair those content problems.

Diagnose the scope before changing anything

Open a card that should contain sound and use Anki's Replay Audio action. On Anki Desktop, the default replay shortcuts are R or F5. If manual replay works, the file and card can play; the likely issue is autoplay or which side of the card contains the audio.

Next, compare three cases:

Preview the card from Anki's browser as well as during review. Also open the note editor and confirm that the expected audio field is not empty. This separates a playback problem from a card that never had a valid sound reference.

Fix Anki audio in a reliable order

1. Try replay before changing autoplay

Anki normally plays card audio automatically. A deck option named Don't play audio automatically disables that behavior, but the replay action should still play audio that is present on the card. The official Anki deck-options guide documents the option and replay behavior.

If replay works, decide whether audio belongs on the front or back. Put it on the front when the card tests listening recognition. Put it on the back when written language is the prompt and sound is feedback. The audio-and-image card guide explains that design choice in context.

2. Inspect the audio field, not only the template

A stored audio reference normally looks like:

[sound:clip-014.mp3]

Keep that reference in a note field such as Audio, then place {{Audio}} on the relevant card side. Field names are case-sensitive, so {{audio}} will not display a field named Audio.

Do not construct a filename in the template with syntax such as [sound:{{Word}}.mp3]. Anki's field-replacement documentation says media references to fields are not supported reliably for checking, importing, and exporting. Store the complete sound reference in the field instead.

3. Run Tools > Check Media on desktop

On Anki Desktop, use Tools > Check Media. The report distinguishes files referenced by notes but missing from the media folder from files that exist but are not used by notes. It can also tag notes that refer to missing media.

The Anki media guide explains what the check scans and an important limitation: it does not discover ordinary media references hidden inside card templates. That is another reason to keep each note's [sound:...] reference inside a field.

If the report names a missing file, changing autoplay will not help. Recover the original audio, reattach it through Anki's editor, or re-export the source deck with media included. Do not rename files blindly; the note reference and bundled filename must still match.

4. Confirm the APKG actually contains the sound

An APKG can include audio, but only when the deck is exported with media included. A valid-looking audio field does not prove that the referenced file was packaged.

Before importing a deck, the free Anki Import Checker can inspect the APKG locally in your browser. It compares audio, image, video, and CSS references with the files bundled in the package, and flags empty media fields or broken template-field references. The file is not uploaded.

If the checker reports that a referenced sound file is absent, obtain a corrected package or re-export the deck from its source with media enabled. The official Anki exporting guide confirms that media inclusion is an export choice.

5. Check that the card template displays the field

Open Cards for the affected note type and look at both the front and back templates. A populated Audio field remains silent if neither side includes {{Audio}}.

Also check whether the audio is only on the back. That card will not play the answer-side sound until the answer is shown. Previewing both sides makes this easy to spot.

When editing a shared note type, remember that a template change affects every note using it. Make a backup before a broad change, and test one representative card before syncing.

6. Let media sync finish on every device

Anki syncs media separately from the collection data. A deck can appear on a second device before all sound files have arrived. Keep the app open long enough for media sync to complete, then test the same note again.

The official Anki sync guide explains that media additions, removals, and replacements are merged across devices. The Anki media guide also notes that incompatible filenames can be skipped during sync and symbolic links are not followed.

If desktop works and mobile does not, reattach the real file through Anki instead of relying on a symbolic link or a manually assembled path. Then sync both devices again.

7. Use a portable audio format when devices disagree

Anki Desktop can play many formats, but the Anki manual describes MP3 audio as the most universally supported choice across desktop, AnkiWeb, and mobile clients. If an unusual format works only on one device, convert it from the original source to a supported format, attach the new file, and update the field reference.

Do not merely change a filename extension. Conversion must produce a real file in the new format.

A missing-audio APKG checklist

Use this short pass before importing or sharing a media-heavy deck:

1. Preview cards from the beginning, middle, and end of the deck.
2. Confirm each populated audio field contains a complete [sound:filename] reference.
3. Verify the card template includes that field on the intended side.
4. Run the APKG through the Anki Import Checker.
5. Export with media included.
6. Import a test copy and run Tools > Check Media.
7. Sync media completely before judging playback on another device.

For a full import workflow, including scheduling choices and mobile steps, use How to Import an APKG File Into Anki. If you are producing cards from video, trim the audio at natural speech boundaries before packaging it.

VidToAnki's private beta works from a permitted MP4 toward an import-ready APKG, with audio, images, and structured fields prepared for review. It can reduce the packaging work, but you should still sample the exported deck and verify that every retained clip is accurate, complete, and worth reviewing.

Anki audio troubleshooting FAQ

Why does Anki audio play only after I show the answer?

The audio field is probably on the back template, not the front. That is correct for a reading card where sound is feedback. Move or add the field to the front only when hearing the clip before the answer matches the card's learning goal.

Why is the replay button missing?

First confirm that the rendered side contains a valid audio field. Anki can also hide replay buttons through its preferences or card styling. A hidden button does not create a missing sound file, so test the Replay Audio action and inspect the note before changing CSS.

Why does audio work on desktop but not on AnkiMobile or AnkiDroid?

The media may still be syncing, the filename may have been skipped, or the format may not be supported consistently across devices. Confirm media sync has finished, run Check Media on desktop, and test an MP3 attached through Anki's editor.

Can an APKG import successfully while its audio is missing?

Yes. The notes and templates can be readable even when a referenced media file was not included in the package. Inspect the APKG contents or run Tools > Check Media after import rather than treating import success as proof that every sound arrived.

The fastest repair comes from identifying which layer failed: playback setting, note field, template, package, or sync. Test them in that order and fix only the layer the evidence points to.
