8. Troubleshooting

If you encounter issues with your S9 Pro Plus Martha, refer to the following common problems and solutions:

  • Verify that the "Hidizs S9 Pro Plus Martha" is selected as the audio output device in your operating system's sound settings.
  • Try using a different USB-C cable to rule out a faulty cable.
  • For Windows users, ensure that the necessary drivers are installed. These can be found on the official Hidizs website.
• Abnormal Volume Increases or Glitches:
  • This issue can sometimes be related to specific audio player applications. Try using a different audio player or a dedicated bit-perfect player like USB Audio Player Pro (for Android) to bypass potential software conflicts.
  • Always adjust the volume gradually using the S9 Pro Plus Martha's physical buttons. Avoid setting the source device's volume to maximum before connecting.
• Electric Noise from 4.4mm Port:
  • Ensure your 4.4mm balanced cable is fully inserted and securely connected.
  • Test with a different 4.4mm balanced cable, as some cables may introduce interference.
  • Try different headphones or IEMs to determine if the issue is with the audio equipment or the DAC.
• Device Becomes Warm During Use:
  • It is normal for the S9 Pro Plus Martha to become slightly warm during operation, especially when playing high-resolution audio or driving demanding headphones. This is part of its normal thermal management.
• Increased Battery Drain on Mobile Devices:
