Samsung TV & Audio HW-Q990C 11.1.4 Channel 546 Watt Soundbar with Dolby Atmos, DTS:X, and Wireless Subwoofer DISTORTION Error Fix: Audio Distortion or Clipping at High Volume

Error code DISTORTION on the Samsung TV & Audio HW-Q990C 11.1.4 Channel 546 Watt Soundbar with Dolby Atmos, DTS:X, and Wireless Subwoofer means: Audio Distortion or Clipping at High Volume. Sound becomes distorted, buzzy, or clips at moderate to high volumes. Causes: (1) volume too high for the driver size and enclosure — reduce volume 10-20%, (2) certain frequencies causing mechanical resonance in the enclosure — try different sound modes (Standard, Surround, etc.), (3) Night Mode accidentally enabled — compresses dynamic range and can cause artifacts, disable via remote, (4) equalizer settings boosted too high — reset to defaults via SmartThings or factory reset, (5) speaker driver physically damaged — voice coil rubbing from previous overdriving, (6) loose internal components vibrating against the enclosure. If distortion occurs at ALL volume levels, hardware fault likely.
