only option available is "dsp". For alsa09, the available options are: "dev",
"buf_size", and "periods". See <\fBhttp://www.xiph.org/ao/doc/drivers.html\fP>
for available options for some commonly used drivers. Options are assigned
using "=", and ";" is used to separate options. An example for oss:
"dsp=/dev/dsp". An example for alsa09: "dev=hw:0,0;buf_size=4096". The
default is "".
.TP
.B write_size <size in bytes>
This specifies how many bytes to write to the audio device at once. This
