Description

In the 7.1.8.9375512768 (Vivox only) viewer when a different audio device became default, voice and in-world audio would switch over to using the new audio device.
Starting in the 7.1.9.10515727195 (WebRTC support) viewer when a different audio device became default, voice switches over to using the new audio device, but in-world audio still uses the old audio device.

Reproduction steps

0. Tested on Release 7.2.1.17108480561 2025.06 on Win11: (tower computer + HDMI monitor with sound)
1. Start the computer with headphones unplugged.
2. Log SecondLife into a WebRTC region.
3. Verify you hear in-world sounds (flying noise, gesture sounds) and voice through the computer speakers (or HDMI monitor)
4. Plug in USB headphones.
5. Verify in-world sounds (flying, wav sounds) and voice are coming from the same output.

Observed: After connecting the USB headset, in-world sound is coming from computer/monitor speakers, and voice is coming from the headset.

Expected: After connecting the USB headset, voice and in-world sounds should be heard through the headset.

Workaround: After relogging the viewer, all audio is coming through the headset.

Note: This is not fixed in Test 7.2.1.17366753186

Note: In the repro case of switching devices by unplugging a device, voice switches to the new default sound device. In-world audio is no longer heard for that session because it remains with the USB headphones which was unplugged. Good to know in the case where someone reports they cannot hear any in-world sounds.

Reopened.
Verified on Second Life Release 7.2.2.17774206511 on Win11/OSX in the scope of https://github.com/secondlife/iqa/issues/550

When the audio output device is changed, voice output correctly changes but the in-world sounds output do not change. An example of this is the dice from the Library or a Sound from the library, or the whoosh when flying.
