DSDPlus Monitor source audio if no sync and signal present

[Radpro]

I have DSDplus running in this mode so i can listen to analogue stations without having to listen to the brrrr noise of DMR. However the first second of the DMR noise is not muted.
Is this a DSD problem or caused by some sort of lag via my SDRduo receiver and SDRuno software.

I hear the same thing. Doesn't matter what dongle I use. It just doesn't mute super fast...
