Why is there no sound coming from my Yamaha YSP-4100 Speaker System?

If there is no sound from your Yamaha Speaker System, first ensure all input and output cables are correctly connected. If the issue remains, the cables themselves might be faulty and need replacement. Also, verify that you've selected the correct input source using the INPUT or DInput selector keys. Check that the volume isn't muted or turned down. Finally, confirm that the signals your unit receives are reproducible (e.g., PCM signals should not exceed 96 kHz sampling frequency) and that connected HDMI components support HDCP copy protection standards. You may also need to set “SUPPORT AUDIO” to this unit in “SET MENU”.
