Title:
  Xoscope doesn't work on soundcard (No valid data sources found...
  exiting)

Status in “xoscope” package in Ubuntu:
  Fix Released

Bug description:
  Starting xoscope gives always the error.

   No valid data sources found... exiting

  I think the problem is located in the changed behavior in /dev/dsp.
  Launching with padsp -d shows:

  utils/padsp.c: dsp_open()
  utils/padsp.c: fd_info_new()
  utils/padsp.c: dsp_open() succeeded, fd=8
  utils/padsp.c: unknown ioctl 0xffffffffc0045006
  utils/padsp.c: freeing fd info (fd=8)
  utils/padsp.c: Draining.
  No valid data sources found... exiting

  xoscope version is 2.0-3.1ubuntu1 on ubuntu 11.10
