[Benjamin Tegge <1198577@xxxxxxxxxxxxxxxxxx>]

The choppy audio accross all channels seems to have been caused by a bad
USB cable. Another cable works and I can hear proper stereo by using the
rear outputs 1/L+2/R or the headphone monitor output.

The only thing that seems to be missing is a proper configuration for
the card from ALSA (/usr/share/alsa/ucm/ or /usr/share/alsa/cards/, or
an special handling in /usr/share/alsa/cards/USB-Audio.conf) so that
PulseAudio can pick it up. The following is an excerpt of what I get
when running `pulseaudio -k && pulseaudio -v`:

Title:
  USB-Audio - FCA610, playback  Pulseaudio/ALSA fails to detect card

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Update:

  The issue still exists and is _not_ releated to BIOS or UEFI firmware,
  as I have tried to get the device working on 3 different hosts. I have
  found that using aplay to play a test file will play choppy audio
  accross all channels (the LEDs at the front of the device flicker very
  fast, where they should only be active for the channels playing
  audio). I tried all options from 1 (-c 1) to 10 (-c 10, the device has
  10 output channels), but the result is always the same:

  $ aplay -D plughw:CARD=FCA610,DEV=0 -c 10 test.wav 
  Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
  aplay: pcm_write:1939: write error: No such device

  The device fails after a few seconds and has to be replugged or power
  cycled.

  Release tested: trusty
  Kernels tested: the latest mainline as of today (3.14.0-999-generic_3.14.0-999.201404130205) and the latest trusty kernel as of today (3.13.0-24-generic)

  I am trying to get the new Behringer FCA610  USB/Firewire audio
  interface to work via USB connection (issue might also affect the
  bigger FCA1616 model). I haven't tried Firewire since my computers
  don't have have Firewire inputs anymore. The device is detected as
  "Device: FCA610  Chip: USB Mixer" in alsamixer but only shows a
  control named "Clock Selector" with the following options: SPDIF
  Input, USB-Bus (SOF), Device Internal Clock. Attached files are from
  my workstation running 12.10, but I have also tried 13.04 and saucy.

  What I expected to happen:
  At least some inputs and (stereo) outputs should show up in alsamixer. Ideally 4 stereo outputs (including pulseaudio profiles for stereo up to 7.1), 2 mic/instrument inputs as well as toslink in and out were expected to be working.

  What happened:
  Only a control named "Clock Selector" is visible in alsamixer (View: F5: All), nothing in pavucontrol or sound settings.
