[Bug 841433] Re: Hotplug of USB 7.1 soundcard not detected properly


So, it seems I've hit this bug, and I'm running 14.04.1.  This is with a
GN Netcom 2000 USB headset.  It worked in 12.04, but I am now hitting
this bug in 14.04.  Is there a udev rule I could add that would
introduce a delay after this device's initialization is started so that
it would be fully initialized by the time Pulse Audio went to look at

  Hotplug of USB 7.1 soundcard not detected properly

Status in “pulseaudio” package in Ubuntu:

Bug description:
  Plugging in a Turtle Beach Audio Advantage Roadie USB 7.1 card shows
  up in the pulseaudio hardware list as "1 Input" "Analog Stereo Input".
  However, once I reboot pulseaudio (killall pulseaudio, gnome session
  autorestarts it), then I get "1 Output/1 Input" "Analog Stereo

  In other words, it works perfectly when pulseaudio starts after the
  USB device has been plugged in, but hotplugging it leads to my
  soundcard being detected as just an input device, not a duplex device.
