After updating to the new version this morning I get no audio at all and the push to talk function is completely broken, even deleting the config and resetting the audio devices to default does nothing at all to help, if i revert back to the previous version though everything works perfectly again, is anyone able to point me in a direction as to why this might be happening?

Could you please send us the contents of the developer console when using the new version?

It may contain a clue as to what the problem is.

Precisely: IsFormatSupported() returns AUDCLNT_E_UNSUPPORTED_FORMAT when the format is not supported in exclusive mode.

See https://learn.microsoft.com/en-us/windows/win32/api/audioclient/nf-audioclient-iaudioclient-isformatsupported.

So the solution would be to turn off exclusive mode?

Only problem there is I have never had exclusive mode set.

Interesting... could you provide brand and model of your sound card, please?

Well... in that case the format we are requesting is not supported and the driver does not suggest a close one.

Could you provide a screenshot of the audio output device properties? Specifically, I'm interested in the format that is set.

Default is the above but I have tried a few others too, just want to be clear this has worked perfectly and still works perfectly on the previous version of Mumble

Without any changes at all to the audio driver and/or settings?

Yep, previous version has worked fine since it was released with no changes between the two.

Same effect here, and while I also do have a Sound BlasterX AE-5 in my machine, it's actually not used and not the default, in use and the default is a Sennheiser GSX 1200. Downgrading mumble to 1.4.287 resolves the issue, upgrading to 1.5.634 it doesn't work, with the exact same settings between the two versions.

@smakibbfb @Fuchs is anyone of you able to compile Mumble yourself in order to do a bisect to identify the root of this issue?
