No Sound or Mono Sound from Analog Output (AUX / RCA)
This guide helps you troubleshoot no sound or mono-only sound issues when using the analog output (AUX / RCA) on your Arylic device.
Before You Start
- Make sure the Arylic device is powered on and actively playing audio.
- Confirm the connected amplifier or speaker is powered on and set to the correct analog input.
- Turn up the volume on both the Arylic device and the external audio device.
Step 1: Check the Cable Type and Connection
1. Confirm you are using a stereo cable, not a mono cable.
2. For 3.5mm AUX output, use a TRS stereo cable (Tip–Ring–Sleeve).
3. For RCA output, make sure both Left (white) and Right (red) cables are connected.
*Using a mono cable will result in sound from only one channel or no sound at all.
Step 2: Verify Left / Right Channel Connection
1. Make sure both left and right channels are connected to the correct inputs.
2. If only one speaker plays sound, swap the left and right cables to test.
3. Check that the amplifier or active speakers are not set to mono input mode.
4. Make sure the device is not muted and volume is above minimum.
Step 3: Check Speaker and Amplifier Settings
1.Make sure the amplifier supports stereo analog input.
2. Disable any bridge, mono, or balance modes on the amplifier.
3. Check the balance control and confirm it is centered.
*Incorrect balance settings may cause one channel to be silent.
Step 4: Test with Another Cable or Device
1. Replace the analog cable with another known-good cable.
2. Connect the Arylic analog output to a different amplifier or active speaker.
3. Test the original amplifier using another audio source.
This helps determine whether the issue is caused by the cable, the Arylic device, or the external equipment.
Notes
- Very low volume may be mistaken for no sound—always test at moderate volume.
Troubleshooting Tips
1. Power off all connected devices, unplug for 30 seconds, then restart.
2. Update the Arylic device firmware if available.
3. Avoid using headphone adapters designed for microphones or mobile phones.
4. If the issue persists, contact Arylic support with your device model and connection details.
