Integer mode not working at start of the application

I’ve a problem with the app. Sorry for my English, I’m Italian.

When I start the application, I can’t play music with Integer Mode activated (I prefer use the Integer mode).

I must disable integer mode, and press play. Then I stop, I come back to Integer mode and activate again. Now it works fine, until I close the application.

Before now I didn’t have this problem.

I include the debug file.

Is there a way to fix it, please?

Check if some other application is using the same device? Fore example some other music player app.

No, no other app use the device.

Then it’s an issue with your DAC. Can you paste the debug info here?

Hello @Andrea82,

Can you try to add a folder to be synced with Audirvana in the Library section of the settings?

Hi Damien, I try but without success.

You now have content in the Library or not at all?

I have content. The problem is the integer mode. When I turn off the dac, close the app, and then turn on… I receive the message “Unable to change to integer mode”.

Have you tried to disable Integer mode in the audio output settings?

When I start the application, I can’t play music with Integer Mode activated (I prefer use the Integer mode).

I must disable integer mode, and press play. Then I stop, I come back to Integer mode and activate again. Now it works fine, until I close the application.
