.... would an .mp3 be played ??

Here is related background: #773

What may work is wait for user interaction on the page and then set enabled='true'.

[andreasplesch]

Here is a build which retries playing until successfull, eg. when the user interacts:

It needs enabled='true' for AudioClip. Please give it a try. I think it would be safe to adopt the fix.

Did that change help ? If so I can merge it.

@npolys Any luck with the sound fix ?

[MarkCallow]

I'm getting

Loading failed for the <script> with source “https://5e84aff60cc298000663822b--x3dom.netlify.com/”

when I try that build with my scene. Is "netlify" a typo?

To answer my own question, I get the same error with netify

[andreasplesch]

Sorry, I should have been more explicit. Try:

This build works while the release build doesn't. Now when I click on Floops the animation and the audio start.

One time after a reload the audio was out of sync but I couldn't reproduce after several more attempts.

Why isn't audio enabled when the startTime is set via an event? For now I've set enabled='true' in the AudioClip attributes.

[andreasplesch]

Thanks for the confirmation.

It turns out startTime is not implemented. I do not know why. Perhaps because it would require an additional check at each tick.

You may be able to route the isActive event from the TouchSensor to AudioClip via a BooleanFilter (since enabling should happen on isActive = false).

[MarkCallow]

If startTime was implemented then I think my sample would have just worked. The sensor click should have both satisfied the browser's user interaction requirement and by setting the AudioClip's startTime started playback. I will file an issue.

When will this fix appear in www.x3dom.org/x3dom/release?

[andreasplesch]

It is already available at

https://x3dom.org/download/dev/

Not sure what the plans for a new release are.
