You press play — video runs fine, but there’s no sound. Or worse, the audio is seconds behind.

Audio issues are among the most frustrating IPTV problems, but they’re easy to fix once you understand why they happen.

1. Check Volume and Audio Track

Simple but essential:

• Tap the audio icon in your player

• Try different audio tracks (AC3, AAC, MP3)

Some streams default to unsupported codecs.

2. Disable Passthrough

Passthrough sends raw audio to your sound system — great if you have a receiver, terrible if your TV can’t decode it.

Go to Settings → Playback → Audio → Passthrough → OFF.

3. Change Decoder Mode

Switch between Hardware and Software decoding.

Software mode often fixes sound lag or silence on older devices.

4. Fix HDMI and Display Sync

Unplug and reinsert your HDMI cable firmly.

If using a soundbar, try bypassing it temporarily.

Use Display → Match Frame Rate ON to sync audio/video timing.

5. Advanced Fixes

If nothing helps:

• Clear app cache and data

• Restart device

• Update firmware

Final Thoughts

Sound problems are almost always decoding or passthrough errors — not your IPTV source.

With the right combination of settings, you’ll get clear, synced audio instantly.
