History
Alexander Leidinger 01bec79c11 * Add locking / MPSAFE 
* Add kernel hint option to disable DXS channels entirely. Report
  from several skype users / Pav Lucistnik indicate that disabling
  DXS may fix lots of pop / crackling noise. To disable DXS add
  hint.pcm.<unit>.via_dxs_disabled="1" to /boot/device.hints.
  Further investigation of the issues regarding DXS showed, that
  the problem is in another (more generic) place, but until the
  right fix is tested/reviewed this may help a little bit.

Added sysctl's to aid testing/debugging:
hint.pcm.<unit>.via_dxs_disabled=X - Disable / Enable DXS channels entirely
hint.pcm.<unit>.via_dxs_channels=X - Limit DXS channels up to X
hint.pcm.<unit>.via_sgd_channels=X - Limit SGD channels up to X
hint.pcm.<unit>.via_dxs_src=X      - Enable / Disable DXS sample rate
                                     converter.
