You're apparently using an alsa application. If it asks you a sound card
name, tell it to use "default". That should then forward the sound to
pulseaudio if alsa is set up correctly.

I don't understand what you're trying to say here. What's the difference
between "application" and "my program" here? If you tell all
applications to use "default", then all applications will use the same
sound card, and your problem is solved?

With pavucontrol you can route each application where ever you want. I
feel that I'm not understanding what you're asking...
