How to set the pulseaudio stream name via ALSA?

Question

I am writing an audio application using ALSA (via QAudioInput/Output) that opens two output streams simultaneously. Both ALSA streams use the pulseaudio ALSA plugin. That also works fine and I can assign them to different output devices in pavucontrol.

How can I set specific names (and/or other parameters) for those streams such that pulseaudio will remember the stream assignment to specific output devices?

The PulseAudio stream names are hardcoded as "ALSA Playback" in the plugin.

To use another then PA's default output device, you would have to create your own ALSA devices.

You mean, adding more "pulse" devices to `~/.asoundrc`? Or writing a separate ALSA plugin? – Tilman Vogel Sep 24 '12 at 19:26
Adding more devices based on the pulse plugin, as described in the README I linked to. – CL. Sep 24 '12 at 22:17
