AudioV2: Play over paused with new options?

a_bolog · June 17, 2026, 5:40pm

When a sound is paused, playing it back with new options does not update them.
Here’s an example:
https://playground.babylonjs.com/#6FZCRD

I want to be able to resume a paused sound with new options, like a different volume and waitTime.
If I stop instead of pause, the options work perfectly. But I need to use pause.

sound.resume({waitTime: 1, volume: 0.3, duration: etc.}) //does not work
sound.play({waitTime: 1, volume: 0.3, duration: etc.}) //does not work on paused sounds

I checked staticSound.ts and as far as I understand it simply bypasses and drops any options if SoundState.Paused?

           * Clones the sound.
           * @param options Options for cloning the sound.
           */
          public abstract cloneAsync(options?: Partial<IStaticSoundCloneOptions>): Promise<StaticSound>;
          
          /**
           * Plays the sound.
           * - Triggers `onEndedObservable` if played for the full duration and the `loop` option is not set.
           * @param options The options to use when playing the sound. Options set here override the sound's options.
           */
          public play(options: Partial<IStaticSoundPlayOptions> = {}): void {
              if (this.state === SoundState.Paused) {
                  this.resume();
                  return;
              }
          
              options.duration ??= this.duration;
              options.loop ??= this.loop;
              options.loopStart ??= this.loopStart;
              options.loopEnd ??= this.loopEnd;
              options.startOffset ??= this.startOffset;

## Problem Reported on the forum: [AudioV2: Play over paused with new options?]…(https://forum.babylonjs.com/t/audiov2-play-over-paused-with-new-options/63649) When a sound is in `SoundState.Paused`, calling `play(options)` or `resume()` with new options ignored them entirely: ```js sound.resume({ waitTime: 1, volume: 0.3 }); // options ignored sound.play({ waitTime: 1, volume: 0.3 }); // options ignored on a paused sound ``` ## Root cause The options were dropped along the resume path: 1. `StaticSound.play()` / `StreamingSound.play()` short-circuited on `Paused` and called `resume()` **without forwarding `options`**. 2. `AbstractSound.resume()` took **no parameters**, so options could not be threaded through. 3. The instance-level `resume()` called `play()` with no arguments. The instance-level `play(options)` already applies provided options correctly (and accounts for the pause position) — the options simply never reached it. ## Fix Thread the play options through the resume path, forwarding **only** what the caller explicitly set so unset options keep their paused values (playback continues from where it was paused): - `AbstractSound.resume(options?)` and the abstract `_AbstractSoundInstance.resume(options?)` now accept options. - `StaticSound.play()` / `StreamingSound.play()` forward `options` to `resume(options)`. - The WebAudio static/streaming instance `resume(options)` passes them into `play(options)`. This is backward-compatible (new optional parameter). ### Note `resume({ startOffset })` on a static sound is added to the pause offset (existing instance behavior), not treated as an absolute seek. Absolute seek-on-resume would be a separate, larger change. For the reported use case (volume / waitTime / duration / loop) the behavior is now correct. ## Tests Added a shared playback test: play a sound, pause it, then `resume({ volume: 0.5 })` and assert the measured output volume is 0.5. Runs for both `StaticSound` and `StreamingSound`.
