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.
