Basic (?) Sound Help

[mduncan@hal.psislidell.com]

Gasp!!,

I'm having a little trouble w/ sound on my Linux (RedHat 5.1) machine.  I've
gone through the HOWTO and commands like:

    cat crash.au >/dev/audio

and 

   cat endoftheworld >/dev/dsp

don't produce any error messages, but  I CAN'T HEAR ANYTHING through the
speakers (which are on w/ the volume turned up incidentally).  Also the results
of:

    dd bs=8k count=4 </dev/audio >sample.au

produce a non-empty file.  There is no microphone, however, so I can't tell if 
the output makes any sense. 

I've booted in DOS and used the vibra16 diagnose utility to confirm the
interrupt and DMA settings.  I can play CD's w/ XCDplay.  I just can't figure
out why this isn't working.  I've copied the results of   dmesg   and  results
of  "cat /dev/sndstat" below in case that tells anyone somthing I'm not picking
up on. Also, for what it's worth, I first noticed this problem after having
installed XCDroast which informed me that it couldn't talk to /dev/dsp.  

Does anyone understand this????  Are there any other diagnostic tests I can
do????  Do I HAVE to re-build the kernel to fix it???

Any help is greatly appreciated.


Pertinant parts of  dmesg:

Sound initialization started
<Sound Blaster 16 (4.13)> at 0x220 irq 5 dma 1,5
<Yamaha OPL3 FM> at 0x388
Sound initialization complete


Results of  "cat /dev/sndstat"
