Error code ARC NO AUDIO on the Samsung TV & Audio HW-B650 3.0 Channel 330 Watt Soundbar with DTS Virtual:X and Bluetooth means: No Sound via HDMI ARC/eARC Connection. Soundbar connected via HDMI ARC/eARC but no audio output. This is the #2 most common Samsung soundbar issue. Systematic fix: (1) verify HDMI cable is in the ARC/eARC-labeled port on BOTH the TV and soundbar, (2) on TV: Settings → Sound → Sound Output → select "Receiver (HDMI)" or soundbar name, (3) enable Anynet+/CEC on TV: Settings → General → External Device Manager → Anynet+ → On, (4) on TV: Settings → Sound → Expert Settings → Digital Output Audio Format → set to "PCM" (most compatible) or "Auto", (5) power cycle sequence: turn off TV → turn off soundbar → unplug both 30 seconds → plug in soundbar first → plug in TV → turn on soundbar → turn on TV. For eARC, use Ultra High Speed HDMI cable and ensure eARC is enabled in both TV and soundbar settings. If still no audio, try optical cable as fallback to isolate the issue to HDMI.
