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

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