I've just noticed that I get nothing more than 'beeps' from my Sunrays.
As per the wiki, I followed everything exactly as shown. I must point
out I even changed perms on /dev/audio /dev/dsp and /dev/mixer to
-rw-rw-rw and still no success.
Those device nodes affect only sound devices on the server, they have
nothing to do with sound for Sun Ray. The Sun Ray audio device should
be created during session login and the pathname of that device node
should be in your session's $AUDIODEV environment variable. You
should also have a 'utaudio' process running under your user ID. That's
the process that collects the sound data from your session's Sun Ray
sound device and delivers it to the Sun Ray.
If your sound apps don't take notice of the $AUDIODEV variable and
always insist on trying to open /dev/dsp or /dev/mixer then you can
preload an interposer library that intercepts calls on /dev/dsp ot
/dev/mixer
and converts them into calls against $AUDIODEV. (Actually against
$UTAUDIODEV, which should have the same value as $AUDIODEV.)
On Linux most sound apps seem to ignore $AUDIODEV so SRSS tries
to use the interposer by default, you should find that your session
automatically gets an LD_PRELOAD environment varable set to
/usr/lib/libc_ut.so.
On RHAS/SLES/JDS2 all of this happens in a script called 0100.SUNWut
that runs during session startup. On other Linuxes I've no idea how or
when this happens. If you don't have a 'utaudio' process running or if
$AUDIODEV and $UTAUDIODEV are not set then you need to figure out
why those things aren't happening.
As a workaround you can run 'utaudio' manually after you've logged in:
AUDIODEV="`utaudio`"
UTAUDIODEV="$AUDIODEV"
export AUDIODEV
export UTAUDIODEV
LD_PRELOAD=/usr/lib/libc_ut.so
export LD_PRELOAD
but that's too much for most users to handle, you really need it to
happen automatically.

Those variables exist, however I don't have the LD_PRELOAD. As Aaron
suggested, I am going to add it to /usr/bin/gnome-session-sunray and see
if that clears it up. It seems both your responses point to the fact
that LD_PRELOAD does not exist and I am now thinking that is the
problem. I will try it and let you know.
