  Modified files:
    sys/dev/sound/pci    via8233.c 
  Log:
  * 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.
