Thanks for reviewing. The reason why I turnd off pulseaudio
is that the latency was unacceptably large, despite the fact
that pulseaudio is preferred over other sound drivers.
Due to this, ffplay missynchronized sound with video.
Also, I guess OSS was previously disabled because it does not
work as expected due to a bug of cygwin:
https://cygwin.com/pipermail/cygwin-patches/2023q1/012134.html
and winmm was enabled instead.
Now, the bug has been fixed and SDL2 gets working with OSS.
Therefore, we don't need winmm support anymore. I think
it is better not to call winmm directly from cygwin apps.
BTW, I tried to modify SDL2 code to minimize the latency of
pulseaudio and it succeeded. So, I re-enabled the pulseaudio
and updated the package.
Could you please review the package again?
