X
XINSTALLING THE DRIVER
X
X1. Run make in the directory with the driver code (sb.c, sb.h, etc...).
X2. su to root, if not already so, and run /etc/insdriver.
X a. Answer . for query asking for the directory of the driver
X files.
X b. Answer sb for the query asking for the driver name.
X c. Accept the default of /etc/conf for the configuration directory
X by hitting return.
X d. Enter any description you like. Maybe: "Sound Blaster Driver".
X e. Answer n to the configuration question.
X3. As root still, run /etc/kconfig.
X4. Make sure the driver is configured into the kernel in the
X configuration menu.
X5. Build a new kernel.
X6. Install the new kernel. This reboots the machine.
X
X
XINSTALLING THE USER PROGRAMS
X
X1. Edit the Makefile in the apps directory.
X2. Run make.
X3. Run make install.
X4. Manually install the man files however you like. The *.1 files are
Xnroff source, while the *.doc files are nroff'ed for those of use
Xwithout.

X Sound Blaster(tm) Driver
X (Copyright 1991, Brian Smith)
X
X
XREQUIREMENTS
X
XThis driver and the associated user programs require a 386/486 system
Xrunning System V 3.2 Unix. It has been tested on ISC Unix versions
X2.0.2 through 2.2.1. I believe it will work correctly on Esix, Intel,
Xand AT&T Unix. SCO is a mystery to me (as well as many others). I do
Xnot believe it will work in SysV 4.0 and above, but the modifications
Xshould be fairly minimal. Remember, though, THERE IS NO WARRANTY.
X
X
XGENERAL INFORMATION
X
XThis driver is for the Sound Blaster sound card designed by Creative
XLabs, Incorporated. The Sound Blaster is a sound card for the
XIBM-PC(tm) type I/O bus. The card is capable of sampling sound from a
Xmicrophone jack from 4KHz to 23KHz (or 24KHz, depending upon which
Xportion of the manual you believe) at 8 raw bits of resolution. It is
Xalso capable of playing samples at speeds from 4KHz up to 12KHz. The
Xboard can play raw 8 bit samples, or 2 bit, 2.6 bit, or 4 bit ADPCM
Xpacked samples. ADCPM is a lossy method of data compression. The
Xsampling and output may be directly driven by the CPU, or it may be
Xdriven by DMA. The card is also capable of playing music through an
Xon-board FM synthesizer chip. The chip may play 9 simultaneous
Xinstruments, or it can play 6 simultaneous voices with 5 additional
Xrhythm instruments. In addition, the board (but NOT my driver) also
Xsupports the addition of 2 C/MS chips. For more information, read the
Xadvertising blurb, errr... manual which comes with the Sound Blaster.
X
XThe driver is capable of utilizing only a subset of the capabilities
Xof the Sound Blaster card. The driver is accessed through three
Xdevice nodes.
X
XThe /dev/sbdsp node accesses the DSP chip which controls sampling and
Xsample playback. Only 8-bit sound is supported thus far. The driver
Xutilizes DMA, and therefore is very unobtrusive to the system load.
XThe ls utility is harder upon the system. Read(2) and write(2) upon
X/dev/sbdsp sample sound and play back sound samples, respectively.
XSeveral ioctl(2)'s control sampling/playback speed, resets, etc...
XThe play_snd utility demonstrates the use of the /dev/sbdsp node.
X
XThe /dev/sbfm node accesses the FM chips. The only access to the FM
Xchips are through ioctl(2)'s. The play_cmf utility demonstrates the
Xuse of the FM chips by (mostly) interpreting and playing CMF files.
XThe various options controlling the voices can be dumped from a CMF
Xfile by the get_instruments utility. Those familiar with synthesizers
Xcan then learn how to create their own instruments. I can't provide
Xdirect documentation, as I believe that would be a violation of
XCreative Lab's copyrights. Those having questions, send me e-mail. I
Xthink it would be OK to answer questions.
X
XThe /dev/sbcms node accesses absolutely nothing. I do not have the
XC/MS chips with which to experiment.
X
XThis driver is merely the rough outlines of what it could be. Support
Xcould be added for oodles of features, like efficiency improvements, and
XADCPM interpretion for the /dev/sbdsp node. If you wish to add to this
Xdriver, please be my guest (after reading the license file). When you
Xhave patches, send those to me. I will then integrate, do rudimentary
Xtesting, and send the patches to Usenet. That way, there won't be
Xbillions of versions of this driver to contend with.
X
XI am not requiring donations to my, no doubt worthy cause, however,
Xthey are willingly accepted. :-) They will help me in future
Xprojects, and if there are enough requests (loudness does not count),
XI will continue work on this driver and write more software to use
Xit.

X.SH SYNOPSIS
X.B play_cmf
X[
X.I file
X]
X.PP
XThe argument must be the CMF file to be played.
X.SH DESCRIPTION
X.B play_cmf
XAttempts to play a CMF file.
X.SH BUGS
XMany CMF files attempt to use Control Change events not understood by the
Xauthor. Therefore, the program does not implement whatever these
Xcontrol changes are supposed to do.

XThe argument must be the sound file to be played.
X.SH DESCRIPTION
X.B play_snd
XPlays raw 8-bit sound files, using shared memory and two processes
Xto double buffer reads and writes. Feel free to use SIGINT (usually
Xcontrol-C) to interrupt the play. Do NOT, however, use SIGKILL or any
Xother signal to terminate the program. This leaves unwanted
Xleft-overs, in the form of a shared memory segment. Use play_cleanup
Xif this happens accidentally.
X
XUse set_speed to change the playing rate of the samples.
