Quick Start

Get from a fresh install to hearing audio through ENFITEK A/V Engineer.

Important: the control you need first is inside a section called SETUP, which is collapsed and sits below several other sections in the window. Open it first, even though it isn't the first thing you'll see.

Step-by-step

Expand "SETUP" and click "Run compatibility scan and refresh devices." This is required, not optional — it's what fills in every device menu on the page and checks that your system can run the app's capture modes.

Check the privacy acknowledgement checkbox. The Start button stays disabled until this is checked.
(Optional) check "Start ENFITEK when Windows starts" if you want the app launched automatically at sign-in.
Go to "SOUND / OUTPUT / ROUTE" and choose a capture mode.

Two modes are recommended for first-time use:
- EndpointLoopback — captures whatever is currently playing on a chosen Windows audio device on this machine. Pick a loopback source endpoint (what to capture) and a destination render endpoint (what to play it out of) — these are commonly different devices.
  Screenshot 4a pending: EndpointLoopback fully configured, source + destination both selected
- Network — receives audio sent from another machine on your network. Set the network receive port (a sensible default is provided) and pick a destination render endpoint. Setting up the sending machine is a separate, more advanced topic not covered in this guide.

Note: a third mode, ProcessLoopback (capturing a single running application's audio), is real but is not recommended as a first path — see Troubleshooting below for why.
Choose a channel layout matching the real speaker count connected to your destination endpoint.

Check the Route status panel. If it reports a problem, Start will stay disabled until it's resolved.

Pending verification: the exact wording this panel shows for specific problems (for example, selecting the same device for both capture and output) has not yet been captured from a real triggering run.
Go to "PROCESSING PRESET" and leave it on Bypass for your very first run. Every other preset is easier to understand once you've confirmed the unprocessed path works.

Go to "CONTROL AND STATUS" at the bottom of the window and click "Start audio."

Look at the VU meter bank at the top of the window. Moving levels there are your real confirmation that audio is flowing — not just the status text at the bottom.

Reading the VU meters and status

The meters show an RMS level in dBFS (not peak), floored at -60 dBFS before any signal is measured. They reflect the fully processed signal — after your chosen preset, EQ, calibration, and master gain have all been applied.
The Master Pre-Amp slider (-24 dB to +24 dB) is a single final volume trim applied after everything else — it is not a substitute for per-channel balance.
The runtime status in the top-right of the window moves through real named states: Stopped, Starting, Running, Stopping, and Faulted. Faulted is the state you're most likely to see if something goes wrong — see Troubleshooting below.

Switching sources or stopping safely

"Safe source switch" does exactly one thing: it stops the current run cleanly, flushing buffers, so you can change your capture mode, source, or destination and start again. Use it any time you want to change your setup while audio is running, rather than just clicking Stop and Start separately.

Troubleshooting

Start audio is disabled and I don't know why. Check, in order: did you run the compatibility scan? Is the privacy checkbox checked? Does the Route status panel show a problem? Have you picked every field your chosen capture mode needs? This is the most likely first-run issue, since the required first step (the scan) is in a collapsed section below the fold.
The device menus are empty. Run "Run compatibility scan and refresh devices" — they stay empty until that has run at least once.
I selected ProcessLoopback and Start stays disabled. This mode has no manual way to pick which application to capture. Instead, it automatically detects a single application that is actively playing audio at the moment you run the scan. If no app is playing audio, or more than one is, this detection can't resolve to one choice. Make sure exactly one application is producing sound, then re-run the scan.

Meters aren't moving even though status says Running. Check your destination device's own volume and mute state in Windows, and confirm you selected the device you actually expected — this is the most likely cause of silent-but-"Running" playback.
Status shows Faulted. Read the error text shown next to the status — it carries the specific reason for the failure.

The app keeps running in the background after I close the window, with no tray icon to bring it back. This is a known issue currently being worked on. If this happens, use Windows Task Manager to end the ENFITEK A/V Engineer process, then relaunch the app.

Further configuration

Once basic audio is working, two optional pages cover deeper tuning — neither is needed for first sound:
