Hope english list would be more useful, than russian.

I need to play a few audio files simultaneously. For example, when I
listen music, Psi should be able to play event sound. The problem is -
can't open /dev/audio: Device busy.

Could you be more verbose? What make you think that I did not read man
aucat?

I think Davids mindreading device is broken, so he couldn't tell you
tried aucat. Mine seems to be misfunctioning too, can you share with
the list what problems you had with aucat in servermode ? Did it give
any errormessages ?

You know, if you assume we can read your mind, we're going to make
some assumptions of our own...

I ran aucat with '-l' key, then I try to play wav file with 'aucat
file.wav' command or 'aucat -s deafault file.wav'.

aucat -s default send.wav
aucat: can't open /dev/audio: Device busy

I'm waiting for step by step advices. It would be good idea to make
suitable issue in the FAQ.

aucat(1) on 4.5 clearly says legacy mode (when none of -i, -o, or
-l is used) will write TO THE DEVICE.  on 4.5, aucat "legacy mode"
does not work with the aucat server.  it's called "legacy mode"

see the BUGS section of sb(4) (and consider getting different
hardware).

you may want to use '-m play' when sarting aucat server.

We just don't care what FreeBSD 4.11 does. We are not trying to do
the same things. Your hardware works on FreeBSD 4.11 because of

[ snip ]

The "LEGACY MODE" section of aucat(1) says that if neither -i nor -o are
given, aucat falls back to legacy mode; legacy mode wants to open the
device directly rather than going through the "aucat -l" server.  Use the
'-i' flag.

I start "aucat -l" in my .xsession and have both gkrellm's mail checker
and psi configured to use the following helper script to play event
sounds.  These event sounds mix into the music stream from mpd just fine.

Here are the steps you asked for:

 * read sb(4) and notice that your hardware is not completely
   full-duplex in 16-bit mode:

     With a SoundBlaster 16 card the device is full duplex, but it can only
     sensibly handle a precision of 8 bits.  It does so by extending the out-
     put 8 bit samples to 16 bits and using the 8 bit DMA channel for input
     and the 16 bit channel for output.

 * read aucat(1) and figure out how to start it in
   play-only server mode 

     -l      Listen for incoming connections on Unix domain sockets.  This al-
             lows clients to use aucat instead of the regular audio(4) device
             for audio input and output in order to share the physical device
             with other clients.  The default socket name is default but other
             names can be used with the -s option.

     -m mode
             Set the server mode.  Valid modes are play, rec, and duplex, for
             play-only, record-only, and full-duplex, respectively.  The de-
             fault is duplex.

   Hint: you probably need ``-l -m play''

 * start it, and play any file to check that it worked,
   possibly read again aucat(1). Hint:

     -i file
             Add this file to the list of files to play.  If the option argu-
             ment is `-' then standard input will be used.


 * if it still doesn't work, search in the archives and
   see if anybody else has the solution of the same or
   related problems

 * if it still doesn't work, check whether related problems were
   solved in -CURRENT, possibly try -CURRENT

 * if it still doesn't work, send a *friendly* e-mail to the list
   showing that you've read the manual, that you understand
   the manual, that you have done what's explained in the
   manual.

 * possibly share the solution you've found, possibly improve the FAQ.

To summarize, just type:

	$ aucat -l -m play

and check that it works:

	$ aucat -i whatever.wav

because you are not using aucat as a server?

by default, psi uses the 'play' command from the sox package to play
sounds (though sox isn't a dependency of the package ... oops).  the
play command can be used with an aucat server.  many ports/packages
can, actually.

The audio(4) device can't multiplex for you, so you have to send all your
sound
output to a user-space program (aucat), which will multiplex it for
you and forward
it to /dev/audio .  The specific option to aucat you need is '-l'

tl;dr running 'aucat -l' will solve your problem.
