Hi,
Just an update on the issue we are having.
It looks like it is a caching issue in Windows 10, where it does not
refresh/update “Endpoint Characteristics” when audio setting are changed.
A work around is to delete the registry keys that store this information.
These can be found in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render
and
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Capture,
under Properties, and the key is “a2a3fff4-353f-407c-9d86-1f9dc7d5a606”.
If you stop your audio device, change the sample rate, then delete the registry
key(s), the device will work at the new sample rate when started.
These keys are owned by “TrustedInstaller”, so deleting via a script is not a
simple task.
For now we are just recommending customers avoid upgrading to Windows 10.
Thanks,
Paul
