config files

System: Debian Wheezy

PulseAudio is configured as a system-wide daemon and does not define usb-dac
while connecting it to the computer.

$ pactl list short cards
0    alsa_card.pci-0000_00_01.1    module-alsa-card.c
1    alsa_card.pci-0000_00_14.2    module-alsa-card.c

After restart pulseaudio daemon (without detaching dec) the device appears in
list cards as it should be:

$ pactl list short cards
0    alsa_card.pci-0000_00_01.1    module-alsa-card.c
1    alsa_card.usb-Burr-Brown_from_TI_USB_Audio_DAC-00-DAC   
module-alsa-card.c
2    alsa_card.pci-0000_00_14.2    module-alsa-card.c

PulseAudio 4.0 from testing (Debian Jessie) has same issue.
