Symptoms

  • Loud pop or static burst when a show starts, ends, or an ad plays
  • Noise happens consistently at transitions, not during playback
  • Sound system is connected via HDMI-ARC or optical
  • Problem is worse with certain apps than others

Likely causes

  • CommonAudio format switching (e.g., stereo content to Dolby Digital ad) mid-streamSound systems can produce a brief pop when the audio format changes abruptly.
  • CommonVolume-leveling mismatch between content and adsAds are sometimes mastered louder, causing distortion at the transition.
  • PossibleSoundbar/receiver's audio passthrough setting mismatched with contentSetting the streaming device to always output one fixed format can prevent smooth transitions.
  • PossibleLoose HDMI/optical connection amplifying the popA marginal connection makes format-switch artifacts more audible.
  • Less commonSound system's own driver protection circuit reacting to the format changeSome speakers make an audible click when protection circuits engage.

What to do

  1. In the streaming device's audio settings, try switching from 'Dolby Digital' passthrough to 'Stereo' to see if transitions smooth out.
  2. Reseat the HDMI-ARC or optical cable connecting the TV and sound system.
  3. Lower the overall volume slightly, since louder levels make transition pops more noticeable.
  4. Update the streaming device and sound system firmware.
  5. Try a different app to see if the popping is specific to one service's ad system.
  6. Test with a different audio cable if you have a spare.
  7. If popping happens on all sources including non-streaming inputs, the issue may be the sound system itself.

When to call a pro

If popping occurs on every audio source, not just streaming, have the sound system inspected by a technician.
