Likely a bug on Microsoft's end, but could also be Firefox doing something weird/underspecified? Also reported to Microsoft here: https://aka.ms/W0vg77

That's already been confirmed by a senior software engineer at Microsoft:

Unfortunately, it has also been confirmed that the issue will not be fixed in the current build, and possibly not in the next build either.

Official response from a Microsoft dev here: https://www.reddit.com/r/Windows10/comments/7kzt7s/psa_if_you_use_firefox_dont_upgrade_to_17063_it/drjvc8w/

More technical explaination here: https://aka.ms/Sz9xy9 (spoiler: they broke an API).

> Windows has several audio volume APIs - IAudioEndpointVolume, IChannelAudioVolume, ISimpleAudioVolume, and IAudioEndpointVolume. These APIs can be used to change the volume and/or mute state of the stream, app, or audio device.
> In build 17063 a change was made to these APIs to have them return S_FALSE (1) if the requested change was a no-op.
> This broke apps (like Firefox) which request changes (that may be no-ops) and then explicitly check the return value against S_OK (0).

Any chance we can see a workaround on the side of Firefox?

Can someone provide the status of this now? I am seeing this error when running some tests on SauceLabs.

Thanks
