SERATO
HAS NO SOUND ON WINDOWS

Serato document a Windows case where "Serato DJ Pro or Lite may not output audio or may fail to connect to certain hardware", and the cause they name is not the audio device, the driver or the cable. It is microphone access. On "Windows 10 & 11" with "Serato DJ Pro 2.6.0" or "Serato DJ Lite 1.6.0 or higher", the application needs permission to reach the computer's built-in microphone, and without it the decks spin, the master light shows signal, and nothing comes out.

Why it is believable. Windows treats audio capture as a privacy matter, and a modern DJ interface is a single device that both plays and records. When Windows refuses the recording half, the whole device can fail to open, and Serato is left drawing a spinning deck with nowhere to send the audio. The symptom looks like a dead sound card. The cause is a permission.

Their procedure is five steps in Windows itself, not in Serato: click Start and type "Microphone privacy settings", open that settings page, "Enable Allow apps to access your microphone", then "Scroll further down the page, and enable Allow desktop apps to access your microphone", and finally "Restart Serato DJ Pro or Lite if you already had them open".

Both switches, not one. The second one, for desktop apps, is further down the same page and is the one people miss. Serato DJ Pro and Lite are desktop apps, so the first switch alone changes nothing.

Then restart Serato. The permission is read when the application opens, not while it runs.

Serato add a caveat worth keeping: "There are still circumstances where connection may fail with your Serato hardware. If the steps below don't resolve your issue, please work your way through the Troubleshooting Connection Issues on Windows guide."

From there the order is the ordinary one for any controller on any software: confirm the unit is the selected audio device in Serato's setup screen, confirm the outputs are pointed at the unit rather than the laptop speakers, and only then look at drivers and cables. The general no-sound order is on its own page, and it applies here once the permission is right.

The microphone fix takes under a minute and needs no download, so it is worth doing even with people waiting. Start, type the setting name, two switches, restart Serato.

If that does not bring the sound back, take the laptop out of the set. Any drive you have already exported plays in the decks with no computer involved, which is the reason this site asks you to carry one. Fix the laptop tomorrow.

And add it to the pre-gig routine: a Windows update can reset privacy settings, so the machine that worked last month is not proof for this gig.
