Hello! I understand your GuitarTuna app suddenly stopped detecting your strings and the auto-scroll of chords isn’t working. Let's work through this together.

First, may I ask a couple of quick questions to narrow down the issue?
- Are you using the latest version of GuitarTuna on your Linux device? (Sometimes updates can help.)
- Have you recently changed any settings related to microphone or sound input on your device?
- Are you tuning an acoustic or electric guitar, and are you using an external microphone or the device’s built-in mic?
- Did this all stop at once, or did it happen after a specific event (e.g., app crash, system update, new hardware connection)?

Meanwhile, here is a step-by-step approach to troubleshoot:

1. Check Microphone Permissions:
On Linux, ensure the app has access to your microphone. Sometimes privacy settings or system updates can block mic input. You can check microphone permissions or test the microphone with another app to confirm it’s working.

2. Restart the App and Device:
Sometimes a simple restart of the GuitarTuna app and your device helps reset any temporary glitches.

3. Test String Detection:
- Try plucking each string individually, muting others, and see if GuitarTuna detects the string. Sometimes resonating strings confuse the tuner.
- If you have new strings, they might need some stretching before they stabilize for accurate tuning1.

4. Audio Input Source:
Make sure that the correct audio input source is selected in your Linux sound settings. If you plug in external microphones or USB audio interfaces, the app must get sound from the right device.

5. Reinstall GuitarTuna:
If the above doesn’t work, uninstalling and then reinstalling the GuitarTuna app can fix corrupted app files or settings.

6. Check for App Updates:
Although you’re on Linux (which might be less common for GuitarTuna), check if there are updates or patches specifically addressing tuning detection or UI features like auto-scroll.

7. For Auto-Scroll Issue in Chords:
- Verify that the song or mode you are using supports auto-scroll.
- Close and re-open that section of the app.
- Some users report the auto-scroll stops working until the screen or page is refreshed5.

If after these, the app still doesn’t detect sounds or auto-scroll, there may be a deeper compatibility or bug issue on Linux. In that case, contacting GuitarTuna support directly ([email protected]) with your device details and exact app version would be best.

Let me know how these steps go or if you’ve already tried any of them! I’m here to help further.

Are you satisfied with this solution so far?
