I'm not sure I fully understand what you'd like to accomplish but using the command-line as listed below makes you access the ALSA device directly, completely by-passing PulseAudio. If you ever want to do some more advanced mixing/routing and even benefit from the Murphy audio policy capabilities, this does not look like a wise thing to do.
If you really want to specifically indicate the device that you want to use as a sink, then I'd suggest you use Gstreamer pulsesink plugin and specify the PulseAudio device that corresponds to the audio card you want to use.
