soundcard.h has been moved by Peter from machine/ to sys/. A commit logs
tells us:
\begin{quote}
<machine/soundcard.h> -> <sys/soundcard.h>, since it's an exported API
that's arch neutral and OSS API and Linux API compatable.
\end{quote}
The link is to prevent breakages. Use #include <sys/soundcard.h> in new
source code.
