First check that all speaker connections are secure, then verify the audio source is functioning, and finally inspect the audio cable for faults.
This is usually caused by a mismatch between the CD‑ROM and sound‑card wiring; one channel may be shorted to ground and needs to be re‑wired according to the manual.
Ensure the power plug is inserted and the outlet is live, check that the audio source and cables are working, and confirm the line‑control unit is properly connected and its volume knob is turned up.
