Programs Needing to Connect to the Default Sound Device
Certain digital programs can only select the default sound card (or at best choose a single card by index).
For example, MMTTY and MMSSTV choose by index. To enable PowerSDR to work with these programs
you will need to change the system default sound card. VAC offers the ability to continue to use your other
audio applications through its Audio Repeater utility, which we will now discuss.
To change the default sound card, in Windows click Start and then Control Panel. In Control Panel, double-
click on Sounds and Audio Devices to open the Sounds and Audio Devices Properties Form:
Figure 158: Sounds and Audio Devices Properties Form
Set up the Default device for Sound playback and Sound recording as shown above. (Midi playback is
of no concern). Click Apply and then OK.
If you now setup your digital program to select the default sound card, it will work with PowerSDR.
