Fix Jellyfin No Sound: Audio Not Working, Missing Audio Tracks, and Codec Issues (2026)

Fix Jellyfin No Sound: Audio Not Working (2026)

Video plays fine but there is no audio. Or audio works on some files but not others. These are among the most frustrating Jellyfin issues.

Why Audio Fails in Jellyfin

Audio issues almost always come down to codec incompatibility between your media file and the client device.

Fix 1: Wrong Audio Track Selected

Many media files contain multiple audio tracks. Jellyfin may select the wrong one.

1. While playing, open the audio track selector
2. Switch to a different audio track
3. If one track works and another does not, the issue is codec-specific

Set default audio language

Dashboard, Users, [User], Audio language preference - set to your language.

Fix 2: TrueHD / DTS Audio Not Playing

This is the number one audio issue. TrueHD and DTS are lossless codecs found on Blu-ray remuxes. Most streaming devices cannot decode them natively.

Fix: Enable audio transcoding

Dashboard, Playback, Transcoding:

• Ensure Allow audio transcoding is enabled
• Ensure AAC and AC3 are checked as fallback codecs

Fix: Add a compatibility audio track

ffmpeg -i movie.mkv \
  -map 0 \
  -c:v copy \
  -c:a:0 copy \
  -c:a:1 eac3 -b:a:1 640k \
  -c:s copy \
  movie_fixed.mkv

This keeps the original TrueHD track and adds an EAC3 track that every device can play.

Fix 3: Audio Passthrough Configuration

In the Jellyfin client app settings:

• Enable Audio passthrough or Bitstream audio
• Select which codecs to pass through (AC3, EAC3, TrueHD, DTS)

Which clients support passthrough

Apple TV and Fire TV cannot bitstream TrueHD or DTS. This is a hardware limitation, not a Jellyfin issue.

Fix 4: No Audio on Specific Clients

Web Browser

• Chrome: AAC, AC3, EAC3, Opus, FLAC
• Firefox: AAC, Opus, FLAC (no AC3/EAC3)
• Safari: AAC, AC3, EAC3

If using Firefox and no audio: switch to Chrome or use Jellyfin Media Player.

Fix 5: Audio Transcoding Failing

docker exec jellyfin ffmpeg -codecs | grep aac
# Should show: DEA.L. aac

If FFmpeg is missing codecs, use the official Jellyfin Docker image which includes a full FFmpeg build.

Fix 6: Audio Out of Sync

• In the Jellyfin player: use the audio delay setting to adjust sync
• If transcoding: enable hardware acceleration to reduce latency

Fix 7: 5.1 / 7.1 Audio Playing as Stereo

• Check client audio settings - ensure surround sound is enabled
• Check Jellyfin transcoding settings - ensure multi-channel output is allowed
• Verify with a known 5.1 file (AC3 is the most compatible surround format)
