Caveats

Section titled “Caveats”
  • Sounds played from a HUD using llTriggerSound are audible inworld. To make sounds from a HUD audible only to the wearer, use llPlaySound.
  • Playing sounds is throttled. If the average number of played sounds per second exceeds the limit (22 sounds/s), all sounds from the object are suppressed until the average falls sufficiently. The throttle is per object, not per link or per script, so multiple links cannot be used to overcome the throttle.
  • Once the throttle is hit, the following error will be shown in debug channel: “Too many sound requests. Throttled until average falls.”

Examples
