Thanks also. This module was not loaded and indeed solved the issue.

Do you mean the plugin which gets activated like this?

pcm.pulse {
    type pulse
}

ctl.pulse {
    type pulse
}

pcm.!default {
    type pulse
}

ctl.!default {
    type pulse
}

This is already setup and works fine indeed for everything but this one application. It will not allow free text entry of an ALSA device, but will instead present only devices listed in /proc/asound/pcm ("real" hardware devices).

I don't care how dirty the workaround is ;) as long as it works reliably to connect this application to PA.
