Unable to change to Integer mode

Connection with external Audio Devices
1

Something has happened and its preventing me from selecting my RealTek Digital Audio Output, with the following message: Unable to change to Integer mode. Im using version 3.5.41 fully registered and under WASAPI, when I select Realtek Didital Audio Ouput, it comes up with: Device Not Connected.
I have my audio output from my PC connected to my Marantz Amp through optical connection.

This used to work fine but for some reason, when trying to play a song, I get that message (above).
Windows 10 64 bit latest version is installed and the operating system is fully up to date.
I only have one folder in the library now. I did import quite a lot of folders and I think it was when I did this, it stopped working.
Any ideas please?

Hello @Alavana,

Can you send me a copy of the “Debug Info”? You can get it in Audirvana Settings>General>Debug Info

Note: By clicking on the Debug Info button, Audirvana automatically copies all its content, all you have to do is paste it in response to this message.

I have a similar issue with “Integer Mode”.
Yesterday everything was fine.

Today I pressed play, the transport started moving and the track started playing.
But there was no sound.

I isolated the problem to “Integer Mode”.

Specifically:
When “Integer Mode” is on, there is no sound.
Turn “Integer Mode” off, and there is sound.
Nothing else changes.

I was having a similar problem last night. I was listening to some instrumental jazz and everything was performing superbly then I started hearing a buzz that got louder and I eventually stopped the music to investigate. I eventually traced it to the lead from the USB 3.port to the DAC on the laptop - not sure why it happened, though - then when I attempted to continue with the album the ‘Unable to change to integer mode’ message appeared. At that stage I was feeling a bit depressed so I decided to turn everything off and go to bed. This morning all is back to normal, so I have no idea what was happening last night.
