Just testing and getting the crackling sound when clicking the test button which plays a musical sound for the Zoom speaker after the cable is connected. In my computer's Sound Panel, 48000 32 Bit Float 2 Channels is not an option for any Playback devices. When I access my computer's Sound Panel, on the Playback Devices tab, for the Realtek High Definition Audio, I have tried both 0 HZ and 0 HZ but that doesn't seem to affect the outcome (crackling sound when testing the speaker button in Zoom after connecting the virtual audio cables).

When I check the settings in the vMix Audio Mixer for each of my audio devices, I see that the Master Audio and Bus A indicate 48000 Hz 16 Bit 2 Channels, but my Blue Yeti Microphone and Audio Line 2 inputs indicate 48000 32 Bit Float 2 Channels. I saw somewhere on Facebook that the bitrates need to match among all audio devices in vMix. (I've not had to use virtual audio cables though). In Wirecast, I've been doing screen captures of Zoom on a second monitor connected to this same PC and have not had any audio issues. Windows indicates my Realtek sound card driver is up to date. My system configuration: Windows 10, i7-6700 quad core processor, 16 GB RAM, nVidia 750-TI graphics card.

I've searched the forum but have not found an answer to this question. I'm new to vMix (just started using version 20 as a trial) but have been using Wirecast for about 10 months.
