There’s a workaround for this. In Windows, open your sound settings, go to volume mixer/app volume (you may need to scroll down), ensure you have Dezzer app open on your pc, find deezer in the app volumes and set the output device to your chosen device (works best if you have an external DAC). Now Deezer will have an exlusive mode over the device. find your device in your sound settings and set your device to the desired sample rate and bit depth, Deezer is cd quality FLAC so I have mine set at 32bits 48000khz. Now you have exclusive mode with it playing the correct sample rate and bit depth as you would for Tidal or Qobuz. Works in exactly the same way, this is just a more manual way of doing it. Enjoy!

Thanks for the tip @el_micko ! 

Anyone else have trouble in windows 11 with it not showing all the apps in the volume mixer?  Apps such as the deezer app?
 

Hi @tino.l, sorry to hear that you are having this difficulty to find Deezer app in the volume mixer.

So far we don’t have complaints regarding this same topic.

When I Google "exclusive mode windows" I found that this setting does nothing, UNLESS you use music player or app that will utilize this feature. Setting this "on" in Windows will only allow for that particular sound device to work in exclusive mode if needed.Indeed to bypass Windows mixer and get a bit perfect output. If you set if "off" and try to use exclusive output in media player - you will get an error.

So the Deezer windows App, does not use any speakers in exclusive mode right,?
