pactl list, ran when system is working as expected (pulseaudio started with DAC plugged int)
Description of problem: I own a USB Digital to Analog Converter (DAC) that I plug into the USB port of my laptop. If the DAC is plugged into the computer on boot, PulseAudio registers the device as iec958-stereo, this is intended behavior. If the USB DAC is plugged in after pulseaudio has been started, the iec958-stereo profile is unavailable, and pulseaudio uses the analog-stereo profile. This renders me unable to change the volume of the device. It is important to note that the system works 100% as expected if the USB DAC is plugged in when pulseaudio is started. As a workaround, I run `pulseaudio -k` and then open pavucontrol to restart pulseaudio. After doing so, everything works perfectly fine.
Version-Release number of selected component (if applicable):
100% reproducible, happens on Arch Linux as well.
Steps to Reproduce:
1. Ensure USB DAC is unplugged
2. Boot Fedora 22
3. Wait until GNOME3 loads
4. Plug in USB DAC
pulseaudio is using the analog-stereo profile for the device and the iec958-stereo profile is unavailable
the iec958-stereo profile is available and active
Again, everything is perfectly fine if the device is plugged in when pulseaudio is started. This issue only occurs when the device is hotplugged
