Re: Voicemeeter or Audio problem after WIN10 update

On Windows 10 1809 I can't set the VoiceMeeter Input and VoiceMeeter Aux Input devices to 48,000khz/24bit/5.1 audio configuration. It reverts to 44,100khz/24bit/2.0 audio all the time. Often these get reset after a minute or so.

I have made some tests in 3 virtual machines with a fresh install of Windows 10 and only VB Potato
Windows 10 1803: works fine
Windows 10 1809: resets settings to 44,100/24bit/2.0
Windows 10 insider 18309: resets settings to 48,000/24bit/2.0

I know it is likely to not be an issue on VoiceMeeters side. I have an HDMI output device that showed similar issues since the 1809 update where the configuration reset to a lower bit rate and stereo configuration. A work around that might help in this situation would be to be able to limit the available audio format settings the driver populates.

well, another issue from Microsoft... you may notify it (i guess by Feedback HUB procedure).
On my side, I have sent an e-mail to Matthew van Eerde & Pete Brown to inform them about this new problem.

I did some more testing on that windows 1809 bug and figured something out that might help someone who is struggling with this issue.

The sound device settings get reset when you press 'cancel' in the channel configuration wizard (where you set your speaker layout). I did that each time in order to verify i had set the correct speaker configuration and therefore reset my configuration for that device. Windows 10 1803 didn't have this issue.

In Windows 10 1809 seems not to be possible to set VoiceMeeter Input and Aux Input both to 5.1/48000khz/24bit at the same time. You will get an error trying to play the test tone on both devices in that configuration. One device in 2 channel mode and the other in 5.1 mode works (48,000khz mode). When in 44,100khz mode, both devices can be used in 5.1 mode simultaneously. This issue does not exist when using VB under the older Windows 10 1803.

Windows 10 1809 also shows some channel and sampling rate options that some devices do not even have. I run an TV/Receiver on an HDMI port on a nvidia card. I have a little box (a HDFury Dr. HDMI) between the computer and the Receiver that runs a custom EDID profile. I have uploaded a custom profile so that the only audio capability reported for that receiver is 48000khz, 24bit and 5.1 audio capability to the PC. This was working fine on w10 1803. Now 1809 shows me also 16bit capability and channel configurations for stereo, quad speakers.
