If your volume knob lights up but no sound comes out, your issue is likely Pin 4/5 (Input) or Pin 10/11 (Output) on the cable. You can splice a standard VGA cable by cutting it open and soldering the wires according to this map.
Connect the of your RCA cable or AUX wire to your desired audio channel pin (e.g., Pin 2 for Subwoofer audio).
This indicates a ground loop or an open ground pin. Ensure that Pin 8 (Audio Ground) and Pin 15 (Shield Ground) are securely connected and have zero resistance.
| Symptom | Likely Wiring Culprit | Exclusive Fix | | :--- | :--- | :--- | | | Broken 6-pin DIN Pin 1 (+5V) | Re-solder the pin inside the molded plastic (tedious) or buy a new cable. | | Volume control is jumpy | Dirty I2C data lines (Pin 3/4) | Clean the 6-pin connector with DeoxIT. The pod's encoder is failing. | | Subwoofer hums, but satellites are silent | Loose ground (Pin 2) on 6-pin DIN | The return path for audio is broken. Re-crimp Pin 2. | | One satellite is quieter than the rest | Wire polarity reversed on the terminal block | Swap the + and - wires on that channel at the subwoofer. | | Burning smell from subwoofer | A speaker wire touched the metal backplate | You have a short to ground. Immediately check your RR/RL wires. |
If you lack a control pod, you can build a bypass cable to use the subwoofer as a standalone amplifier. According to enthusiasts on EEVblog and HifiGuides Forums : logitech z5500 wiring diagram exclusive
