After I finish listening to foobar2000 through the asio driver and I even close the player, the sound in the headphones and the microphone does not work. I have to turn off and turn on the playback windows device "speakers" and "microphone" - after that it works.
 
Nu Audio driver 0.2.1.10 FW v0.32 / Windows 10 x64 LTSB / foobar2000 v1.4.8

Which driver and firmware are you using?
 
I have seen some users report odd issues with LTSB.

Latest driver 3-13-2020 Audio Driver - EVGA NU Audio 0.2.1.10 and FW v0.32. LTSB licensed and with latest updates too.

And sometimes after listening to the microphone and the sound starts to work itself without turning on / off the devices in windows, and sometimes only the speakers work and the microphone needs to be turned off and on.

Which microphone apps/programs are you using?

I described the problem completely, it is not related to any particular program because the recording/playback device in windows does not make sound, tomorrow I will record you a video of the problem for clarity. And if you don’t listen through the ASIO driver, then such a problem never occurs, it only after listening with the ASIO driver.

I understand, and appreciate a video of the problem.  Our Audio team requested the information regarding the programs you're using, so that they can make sure they're also testing using the same programs, even if it the problem occurs on anything you try.

Hi, I confirm the problem, after listening through the asio driver, there is no sound on youtube, for example. I seems, that asio is still working.

 I hope this will be completely clear to your developers, I also gave comments with time codes.

At 1:08 and 2:58 it’s clear that no software is needed for testing and recreating the situation since there is no sound in the Windows OS itself!

PSS sorry for strobe its blur reduction.

Just to mark it, I also run into the same issue. Win10, Nu Audio Pro 7.1, Foobar through ASIO, leads to no sound in Windows until I disable the Nu Audio in the sound devices and restore it again.
