>Description:
When compiling current versions of Wine, I ran into the problem
that FreeBSD does not feature SNDCTL_DSP_HALT in its OSS stack.
The standard documentation at
http://manuals.opensound.com/developer/SNDCTL_DSP_HALT.html
notes that
In the earlier OSS versions this ioctl call was called as
SNDCTL_DSP_RESET. This name is still valid but for clarity
reasons it is not recommended in new programs (designed for
OSS 4.0 or later).
Indeed FreeBSD features SNDCTL_DSP_RESET, so this should just
be a matter of something like the patch below?
(I'm a ports committer, not src, and cannot test/commit.)
