Thanks! In regards to point 3, I'm trying to get information from a udev sound subsystem device to be used with alsa snd_pcm_open.From my research, it seems best to use udev for hotplugging sound devices and alsa for retrieving information about the device, i.e. udev just triggers an alsa rescan of audio devices.

Before writing the udev rule, try to observe what happens when you plug the USB audio devices in, running: udevadm monitor --kernel. and post the changes after the plugging in of the audio device. Do the same again running: udevadm monitor --udev --property. post the output when you plug in the device. Last edited by berbae (2013-11-24 10:59:00)

Disabling PulseAudio often leads to more problems than it solves. A more effective solution is to tell PulseAudio to ignore a specific device using udev rules. udev is a device manager for Linux, and you can give udev instructions to apply custom configuration for specific devices.
