Is your Sound card set up such that it conforms to the Sound-HOW-TO
LDP document.
I presume that `/dev/dsp' symbolicly links to `/dev/dsp0' and
`/dev/audio' symbolicly links to `/dev/audio0' or something similar.
If this is true `cat chirp.au > /dev/audio' will work, right?
If not true then check your DMA and Interrupt setting from the
Sound-HOW-TO' document. I think the command is `cat /proc/interrupts'
and `cat /proc/devices'.
First, I cannot see how the JDK cannot find your audio device, because
it will need a `/dev/audio' device file, and because the current JDK
1.1 can only play Sun Audio files. Second, writing a program to play
8bit through `/dev/audio' is very easy to implement.
You call open("/dev/audio",...) and save the file descriptor handle
and set the flag `ioctl(...)' to set the sampling rate to 8000Hz.
Create a buffer for audio clip , read your audio clip from disk in to
buffer (just like a text file) and `write()' the buffer's contents
into the file descriptor `/dev/audio' until the contents are
exhausted.
In other words it is as easy as writing a program that copys one file
to another with a few caveats empors. Hence I do not think it is JDK
is a fault. Your configuration probably is.
BTW: XGalaga is an arcade game on Linux, which can play sounds!
You might try any program which you can found, that can play sounds
like SoundStudio (written in Tcl/Tk/C ), XSox, Vrec, Vplay, etc.
Particularly anything that plays `.au' files. Look for players in the
Linux Sound & Midi pages for more infos `

I cannot get java-linux to make any sound using the AudioClip.play() method
When I run the any applet which should play sound, when the sound is to play I g
et:
no audio device
audio player exited
(running with -debug, yeilds no additional information)
I can play sound with other applications.
The appletviewer (.java_wrapper) has setuid root
I have a /dev/dsp and /dev/audio
IS JAVA-LINUX LOOKING FOR SOMETHING ELSE!!!
Do these devices need some special characteristics?
I need some specific info on HOW blackdown implements sound,
what does Blackdown's JVM do?!

I've downloaded applets written by James Gosling for sun for the purpose of
showinghow easy it is to play a sound. It doesn't work! Nothing works, not from
O'Reilly
nothing I've written works, see goofy attached files.

Excellent Idea!Did that!
Got the latest Driverrs from OSS!
got old code out of the way, untarred new code
ran make xconfig, make dep, make clean, make zImage, copied image, ran /sbin/lil

Still doesn't work.

If I can't figure out how this works, the Microsoft JVM is how all our code will
be
tested!
I will be staying late at work to reformat the HD on our linux box to re-install
windows 95
