Bug 274385 – [WebXR] AudioContext not playing audio after XR session is started

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: WebXR

We've found tha AudioContexts don't appear to output audio after an XR session is started. Calling 'resume()' on the context after the session as started unfortunately does not help.

Than k you for the report. Would it be possible to provide a reproducible test case, so that we don't have to re-create it from the description?

My apologies for the delay. I'll have access to our AVP tomorrow and will provide a test case.

Test case showing AudioContext issue on AVP

This index.html file has two buttons. Clicking the first starts an AudioContext and plays a sine wave. (Sorry for how annoying the sound its but it's easier than attaching an audio file). The second button starts an XR session. Note that, for simplicity, the file does not set up any 3D rendering, it just requests the session.
On AVP clicking the first button starts the audio playing, but when the second button is clicked (and the XR sessions starts) the audio stops playing.
On the Quest and PICO browsers the audio continues to play once the session is started.

Just a wee note to say that this appears to be fixed in the Vision OS 2 preview build :-)
