Transfer from Asio to non-exclusive Wasapi fails when sample rate of the track doesn't match the sample rate set in Windows sound settings

Help Needed please !!!

Are there please people wanting to participate in a little test (steps below) and tell me if they experience the same unlogical behaviour ? It’s to determine if Roon has a bug or if my driver has one. (I only experience this bug in Roon, not in other players.)

Thanks.

Roon on Windows, Dac connected over USB to laptop/pc
(Dac is Matrix Element X but you can test with whatever dac you own)

Preparation :

  1. Transfer to a Wasapi driver zone
    (click Speaker symbol right bottom screen, click two arrows, select Wasapi)
  2. Make sure Wasapi is in non-exclusive mode
    (Settings>Audio>Wasapi tab : gear symbol>Device Setup>
    Exclusive mode checkbox : NOT checked)
  3. Make sure all DSP is OFF (no upsampling at all)
  4. Restart Roon (this is to make sure Asio hasn’t been used yet by Roon at the beginning of this test)

Test:
While in Wasapi zone …
5. Try playing some tracks with different sample rates.
All should play over Wasapi and the dac should show one particular sample rate.
(this is the sample rate that is set in windows sound settings)

  1. Transfer to Asio driver (zone)

  2. Play the same tracks again
    All should play and the dac should now show their particular sample rates

  3. Tranfer back to the Wasapi driver (zone)

  4. Play the same tracks again

Unlike in step 5 where all tracks played flawlessly, no only the tracks with the exact same sample rate as in Windows sound settings (see step 5) are playing, for all the others I get no sound at all.

Can someone verify if they experience the same issue?
(Remember the Wasapi driver has to be in non exclusive mode for this test.)

Help please ! Thank you.
