No Input or Output Signal in BIAS X

If you're not getting any input or output signal in BIAS X—even with the correct audio settings—try the steps below to troubleshoot common causes.

Troubleshooting Steps

1. Check Cable and Instrument Connection

   • Ensure your instrument is securely plugged into your audio interface.
   • Swap cables or try a different instrument to rule out hardware faults.

2. Grant Permissions on Your Operating System

   • macOS:
     • Go to Apple Menu > System Settings > Privacy & Security.
     • Enable access for Microphone and Files and Folders (look for BIAS X under each section).
       
     • Ensure the microphone mode is "Standard".
       Change the sound input settings on Mac
        
   • Windows:
     • Go to Settings > Privacy & security.
     • Under App permissions, select Microphone.
     • Ensure microphone access is enabled for both the system and apps.
       

3. Verify Input/Output Channels

   • In BIAS X, navigate to Audio Settings > Input/Output Channels.
   • Select the channels that match your audio interface (e.g., Input 1, Output 1/2).

4. Check Noise Gate and Output Settings

   • Make sure the master input level is turned up and the Noise Gate is turned off.
   • Ensure your master output or amp volume isn't muted or too low.
     

5. Confirm Preset Signal Path

   • Check that your preset includes an amp or other signal chain modules.
   • Avoid muted or missing blocks that could break the signal flow.
