The best way to fix missing audio after export in DaVinci Resolve is to ensure the audio tracks are active on the Deliver page, route the audio outputs correctly in the Render Settings, and verify your codecs.

Here are the direct methods to fix missing audio after export in DaVinci Resolve.

## What is the fastest way to route audio tracks for export?
If your exported video plays perfectly but has absolutely zero sound, DaVinci Resolve likely rendered the video stream but failed to process the audio stream because the audio output tracks were unassigned on the Deliver page.

To quickly route audio tracks for export:
1. Open the **Deliver** page (Shift+8).
2. Go to the **Render Settings** panel on the top left.
3. Click on the **Audio** tab next to Video and File.
4. Ensure the checkbox for **Export Audio** is checked.
5. Under the **Output Track 1** section, ensure the dropdown menu is set to **Main 1 (Stereo)**.
6. DaVinci Resolve will now perfectly map all of your timeline audio channels directly into the final exported video file.

## How do you fix muted or bypassed tracks?
If the exported video has some sound (e.g., music) but missing dialogue, DaVinci Resolve processed the audio stream, but the specific dialogue track on your timeline was accidentally muted or bypassed during the editing process.

To fix muted or bypassed tracks:
1. Go back to the **Edit** page (Shift+4) or the **Fairlight** page (Shift+7).
2. Look at the track headers on the far left side of your timeline.
3. Locate the `M` (Mute) button on every single audio track. Ensure none of them are highlighted red.
4. Check the `S` (Solo) button. Ensure none of them are highlighted green (which mutes all other tracks).
5. DaVinci Resolve will instantly restore the playback of those tracks, allowing them to render out correctly.

## How do you fix codec and format mismatches?
If the exported file has sound on your computer but is completely silent when uploaded to YouTube or played on a TV, the audio codec (e.g., Linear PCM) was exported in a format that the playback device simply cannot decode.

To fix codec and format mismatches:
1. Open the **Deliver** page (Shift+8) and go to the **Render Settings** panel.
2. Click the **Audio** tab.
3. Ensure the **Format** dropdown is set to **QuickTime** or **MP4**.
4. Change the **Codec** dropdown to **AAC** (Advanced Audio Coding) or **MP3**.
5. Set the **Data Rate** to `320 Kbps` or higher.
6. Click **Add to Render Queue**. DaVinci Resolve will encode the audio stream using universally compatible compression, guaranteeing the sound works on any platform or device.
