Description

Switching audio devices after login has never been very reliable but recently, it seemed to work ok.

After this release and/or WebRTC that no longer seems to be the case. If I switch from speakers to Airpods Pro after log in using preferences, the Mac thinks it's switched and non-Viewer audio does appear in the earbuds but the audio (system audio and voice) still output to the speakers. I tried many times.

I know Bluetooth devices can sometimes be problematic so I also tried a pair of speakers with a 3.5mm jack and the same thing happened. The Mac UI told me "External Speakers" were in use but the Viewer did not switch output.

Reproduction steps

Set your audio output device to the built in speaker.
Start SL and log in
Put on Airpods Pro (or probably another audio device)
Switch to them them using the macOS UI
Go to the Viewer and using Preferences -> Sound & Media -> Voice Input/Output devices and switch to them also. (They DO appear in the list of devices)
Note that audio/voice still comes out of the speaker
Expected the output to come out via the Airpods Pros

I noticed that the Voice Server Version value was no copied using the Copy button in Help About.

Confirmed that it was:

Voice Server Version: Secondlife WebRTC Gateway

That must be a different bug?

I don't think it's WebRTC related - that just coincides with the Viewer release.

I tried the repro again on several regions that used VIVOX and the result was the same.
