Super basic instructions for Voicemeeter and digi mode software audio connections

This should work for most any common ham software that needs to move audio to/from Thetis/PowerSDR. These are the most basic settings. There are layers and layers beneath this for various tweaks. But this should at least get you to square one: audio moving reliably between Thetis/PowerSDR and such app's as WSJT-X, Fldigi, VarAC, etc.

For this to work you need to be running either Voicemeeter Banana or Voicemeeter Potato, not the base Voicemeeter version.

Step 1: Install Voicemeeter Banana or Potato. The only difference between them is the number of audio channels supported.

Step 2: REBOOT!

Step 3: Make every virtual audio device installed by Voicemeeter run at 48KHz. This is IMPORTANT!

Go to the Windows Sound Control panel. Open EVERY Voicemeeter related device in turn on both the playback and recording tabs, select the advanced tab, and set it to 48KHz, 2 channel mode. 16 or 24 bits doesn't matter, choose one.

Step 4: Configure Voicemeeter and PowerSDR/Thetis.

Run Voicemeeter FIRST. Then start PowerSDR/Thetis.

You need to assign Thetis to one Voicemeeter virtual channel, and WSJT-X to a different Voicemeeter virtual channel, then connect them to each other in Voicemeeter. You only need to do this once, Voicemeeter will remember. You can also go into the Voicemeeter settings and set it to run on startup, this will help you not forget to run it FIRST.

1. In Voicemeeter, click the A1 Hardware Output button and assign it to your default PC speaker audio output.

2. In PowerSDR/Thetis, assign the Voicemeeter VAIO channel to both the VAC1 input and output. Use the MME driver. Turn stereo on. Select 48KHz sample rate. Make the buffer size 2048. Leave the four manual boxes unchecked. Leave all gains at 0dB.

3. In your digi mode program (e.g. WSJT-X) assign the Voicemeeter Aux channel for both input and output.

4. In Voicemeeter click the "send" buttons (marked A1 through B2 or B3, depending on the version) as follows:

a) On the Voicemeeter VAIO channel click the B2 button, this will send audio from PowerSDR/Thetis to WSJT-X.
b) On the Voicemeeter Aux channel click the B1 button, this will send audio from WSJT-X to PowerSDR/Thetis.

5. Leave all other buttons in Voicemeeter OFF. Leave all Voicemeeter volume sliders at the default 0dB.

6. In PowerSDR/Thetis enable VAC1

This should get you basic audio functionality running.
