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.
