To set up the device, three functions must be called in the correct
sequence:
\code{setfmt} to set the output format,
\code{channels} to set the number of channels, and
\code{speed} to set the sample rate.
\begin{enumerate}
\item \code{setfmt()} to set the output format,
\item \code{channels()} to set the number of channels, and
\item \code{speed()} to set the sample rate.

Returns a bitmask of the audio output formats supported by the
soundcard. On a typical Linux system, these formats are:
AFMT_MU_LAW---a logarithmic encoding. This is the default format on
/dev/audio and is the format used by Sun .au files.
AFMT_A_LAW---a logarithmic encoding
AFMT_IMA_ADPCM---a 4:1 compressed format defined by the Interactive
Multimedia Association.
AFMT_U8---Unsigned, 8-bit audio.
AFMT_S16_LE---Unsigned, 16-bit audio, little-endian byte order (as used
by Intel processors)
AFMT_S16_BE---Unsigned, 16-bit audio, big-endian byte order (as used by
68k, PowerPC, Sparc)
AFMT_S8---Signed, 8 bit audio.
AFMT_U16_LE---Signed, 16-bit little-endian audio
AFMT_U16_BE---Signed, 16-bit big-endian audio

Most systems support only a subset of these formats. Many devices only
support AFTM_U8; the most common format used today is AFMT_S16_LE.
