No Signal
Short answer: if FeedBack shows no input signal, solve that before tuning, calibration, or scoring.
First Checks
- Confirm the instrument, cable, mic, or interface is plugged in.
- Confirm the interface gain is up.
- Confirm the input is not muted.
- Confirm the operating system can see the device.
- Re-select the input in FeedBack.
- Try the tuner as the simplest signal test.
Device-Specific Checks
| Setup | Check |
|---|---|
| USB instrument cable | Make sure it is selected as input, not output. |
| Audio interface | Pick the correct channel. |
| Microphone | Check OS microphone permission. |
| Virtual device | Confirm the source app is sending audio to it. |
If Signal Appears in the OS but Not FeedBack
- Restart FeedBack.
- Re-select the input device.
- Try another driver path if available.
- Export diagnostics after reproducing the issue.
