June 2020 Win10 Update Killing Audio

Hi. I’ve updated Win10 with the June KB4560960 Windows update and associated Windows feature enablement update KB4517245, twice and both times it kills my audio.

In Sound Settings, audio output is still picking up sounds but nothing's coming through my Sound Blaster ZxR sound card to speakers or headset.

I’ve tried updating drivers via Troubleshooter, from Device Manager and direct from manufacturers website but nothing works.

I’ve tried multiple different settings and changes but sound still doesn’t work.

Web research shows this happened a lot due to Windows updates earlier this year but those updates never had any impact on my audio at all.

I’ve tried numerous fixes that people recommended for the earlier updates like deleting the Sound Card and drivers via Device Manager and rebooting but none of those solutions have worked. The only thing I’ve been able to do to get sound working again is to roll back to the previous version of Windows.

Any assistance would be greatly appreciated.

Hi. Thanks for this however I'd already gone through most of these pages - other than the last link. The only Audio related item on these pages is related to Conexant ISST Audio / Drivers which I don't use, afaik. The drivers used are only the Sound Blaster one's - or are Conexant ISST Audio / Drivers inbuilt into Windows and so are affecting the Sound Blaster Card? Or am I missing something?

These are some trial and error steps:

1) Upgrade the BIOS: 1803 > 2302
SABERTOOTH Z87 BIOS & FIRMWARE | Motherboards | ASUS Global


2) Check drivers / codec
1) Check the component manufacturer website for drivers and any codec
2) download the driver to the desktop
3) uninstall the current driver
4) install the new driver

3) if the above fails test Microsoft catalog drivers:

Great, thank you. Some good tips for stuff I haven't tried yet.
